UPDATE: 01/13/11 Scrap Most of this,
got a 3G working image works 10tmes better than anything i have seen.
UPDATE go here:http://forum.xda-developers.com/showthread.php?t=912544
have networking with hamachi, ssh works coolstuff:
trying to put it together (steps to create, and emulate on your computer, an image to get worken on your phone,) it works for the epic also which i have to say i prefer because of the slide-out, ya no wat. as soon as possible 2 DAYS TOPS
To Install Ubuntu Maveric on your Phone:
Of course you must have a rooted phone, since your rom must use a kernel with Loop support, I have only tested this on CyanogenMod Nightly build 199
make sure you have busybox installed
To create the image You have to start with a computer running Ubuntu or setup Virtual Box on a Windows computer,
or go here http://w3.impa.br/~gabrield/data/ubuntu-arm-development-rootfs.tar.bz2 to download the prebuilt one ( i havnt tested it)
1: Open Terminal in Ubuntu
2: Enter:
sudo apt-get install rootstock. After installing Rootstock, again in ubuntu terminal,
Enter,
3: sudo rootstock --fqdn ubuntu --login ubuntu --password ubuntu --imagesize 2G --notarball .
You can change login and password to your desire and also change imagesize 1G 2G and soforth
Your ubuntu-arm.img will be created in about 15 min or so. Take that arm.img and use Ark to crush it down to under 200meg if you would like or and or change name to ubuntu.img.
Using file manager, Create a folder (on your phone) /sdcard/ubuntu
and transfer ubuntu.img to your sdcard folder, ubuntu.
Copy the following text including the (#) and paste into notepad++
(get it http://notepad-plus-plus.org/download) or in linux gedit or Eqvlnt.
Save as sdcard/ubuntu/bootubuntu (no extension)nothing more.
#modprobe ext2

Next update: How to network with Hamachi
It does work
ill give this a try tommorow..
Gonna, maybe, dive in.
Fire up an ubuntu image and then connect to it with vnc... I think I'll wait for the movie to come out and save the battery life. Hey wait, thats an idea. We could make a video of someone using ubuntu, and then play it on our phone so it feels like ubuntu. Might even do better on the battery life / "useful" factor.
(I've seen this method before, so keep in mind I am poking fun at the people who would want to do this and not you for sharing this with us.)

UPDATE:
FIXED WILL POST FIX SOON (had to use MAKEDEV)
THIS IS GREAT YAHOOOO
Hi i was hoping you could help me with this problem:
I am using (on a dedicated ubuntu computer with Maverick edition)"https://wiki.ubuntu.com/ARM/RootfsFromScratch" example to create a qemu image using "sudo rootstock --fqdn ubuntu --login ubuntu --password ubuntu --seed nano --notarball --imagesize 3G".
I have also used the "sudo project-rootstock/rootstock --fqdn ubuntu --login ubuntu --password ubuntu --seed nano --notarball --imagesize 3G"
and: "sudo ./rootstock --fqdn ubuntu --login ubuntu --password ubuntu --seed nano --notarball --imagesize 3G" way.
They all work great. I am able to load the image with qemu, got ssh setup and working alls great in life.
The problem lies HERE.......
I am using these images (mostly for fun), to setup ubuntu onto my Evo and Epic smartphones using this method: "http://forum.xda-developers.com/showthread.php?t=881401" to chroot the image.
ITS AWSOME IT WORKS AND LOTS OF FUN!
well sorry for screaming but it really excites me this open source Ubuntu Stuff. (i am a win user, but I found a new toy)
Using the prebuilt image everything works excellent (except for the small image size 2G) that is why i need to use my 3G built image.
My problem: My built image works flawlessly as well, with one exception, (that i have noticed) is, inside ubuntu (on my phone chrooted with android) the terminals do not have a prompt# only black, square curser, and will not except input. I have to use the terminal program inside android to apt-get and such.
I have noticed with my build images, using apt-get during install, i see "Can not write log, openpty() failed (/dev/pts not mounted?)"
error. My reserch says terminals wont work if system cannot write to /dev/pts.
The prebuilt image does not have this issue.
What is the differance with the prebuilt that is offered here "wget -c http://w3.impa.br/~gabrield/data/ubuntu-arm-development-rootfs.tar.bz2", and the images I create using the steps outlined in the article.
Is there modifications prior to or after creation, or is this someting different altogether.
I really have been pulling the little bit of hair i have left out of my head for a week now
HELP.!!!
p.s. I have tried all builds etc; karmic,lucid same results
Try mounting dev/pts says it is mounted but busy
To Homefix :
Did you try "sudo apt-get install ..." ?
To change bash prompt did you try "export PS1=#" ?
What is an output of "id" command? If you get anything other than root, add that user to root group, or just "su" maybe?
Can someone please post some pics or a video of this working?

Talk in the CM7 threads has revealed that many people remove apps from CM7 before flashing/after flashing/using an update zip. This thread has a quick and easy method to remove apps (and other things) from CM7 on boot using an init.d script.
This method requires s-off (as the system is mounted as rw) and requires a little knowledge of android, however I will produce a 1 time only flash zip if people need it.
The following script is used and I will explain it below and what to modify;
If using Windows, don't use Notepad. I suggest Notepad++
/system/etc/init.d/50rm
Code:
#!/system/bin/sh
#mount system rw
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system;
#apps to delete
#send installed apps to /data/packages
pm list packages -f > /data/packages
for i in CarHomeLauncher LiveWallpapers LiveWallpapersPicker Protips;
do
if [ -e /system/app/$i.apk ];
then
rm -f /system/app/$i.apk;
grep $i.apk /data/packages > /data/pname;
pname2=$(sed 's/\(.*=\)\(.*\)/\2/' /data/pname);
pm uninstall $pname2;
fi;
done;
rm -f /data/packages
rm -f /data/pname
#delete camera_click sound
if [ -e /system/media/audio/ui/camera_click.ogg ];
then
rm -f /system/media/audio/ui/camera_click.ogg;
fi;
#mount system ro
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system;
Save the script as /system/etc/init.d/50rm (adb push 50rm /system/etc/init.d/50rm) and change permissions to 750 (adb shell chmod 750 /system/etc/init.d/50rm).
Next, so that this script is kept through flashes of new CM7 versions, we add it to the custom_backup_list.txt found in /system/etc/ (if you don't have one, create one).
/system/etc/custom_backup_list.txt
Code:
etc/init.d/50rm
There are two situations to show how things can be deleted:
1)#apps to delete
The line to change here is the for i in ... line (10) where there is a list of app names to uninstall.
Change names to what you want to be deleted from /system/app. Do not include .apk in the name.
2)#delete camera click sound
This is an example of how to delete other files that are wanted to be deleted. As an example, I have put the camera click sound. The full directory of the file will be needed.
What the script does:
The script will check if these files are there and then delete them. With the system apps, I have put in a script that should uninstall the files using the package manager (which I think is working, but am currently testing it because I'm not sure package manager can be run whilst booting, but post-boot my pm list packages -f reveals none of the packages)
Requests:
If anyone has a better, more efficient way of using the pm to uninstall the apps, please mention it. I am a novice when it comes to shell scripting and can only go by what I have done so far.

Script - http://bit.ly/golKIb (right click - save link as - check there is no file extension) - adb push 50rm /system/etc/init.d/50rm; adb shell chmod 750 /system/etc/init.d/50rm

Could anyone write a procedure that checks /system/build.prop, finds the line "ro.sf.lcd_density=240" and swapps it for "ro.sf.lcd_density=210"?

Already done that. Once again, its not the cleanest way of doing things, but its as much as I know.
Change LCD Density on Boot
Code:
#!/system/bin/sh
#change lcd_density and reboot if new install
density=$(grep ro.sf.lcd_density=240 /system/build.prop);
if [ $density = "ro.sf.lcd_density=240" ];
then
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system;
sed -i 's/ro.sf.lcd_density=240/ro.sf.lcd_density=210/g' /system/build.prop;
mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system;
reboot;
fi;
What the script does:
Checks the LCD Density and if it is 240, it will change it to 210 (or whatever value people want by changing ro.sf.lcd_density=210 to the denisty they want). It then reboots immediately (whilst still on splash screen) so that the new density is loaded when you boot the phone.
Why is this needed when there are apps on the market?:
Many of the apps on the market need to be re-run on new rom flashes or are not permanent. This can be made permanent by adding to the custom_backup_list.txt and will be done every new flash in CM7.
Is this way better than deleting apps/sounds before flashing, or is it just alternative?
Personally I find it more easy to delete apps and other stuff via adb when the rom is instaled.

Its an alternative way that does it for you. All you have to do is put the script on your phone, add it to the custom_backup_list.txt and let the script work for you.
iinga, thanks!
Why? Because https://market.android.com/details?id=lv.n3o.lcddensity (for example) doesn't seem to work after reboot, and it has slightly different behavior (check out the keyboard for instance). The build.prop method is the "cleanest" one.

Predictably, it didn't help.
No way would mounting /system as RO be performed twice - because the script terminates after any of them one way or another.

I know it wouldn't perform twice, however I was wondering why it fails to run the script.
It has been working for me, but now trying to work out what is different is difficult.

Nope. Same thing with your script. I even tried granting the script maximum permissions - useless.
Can anyone else verify the script actually works?

Off course
A detailed reproduction of my steps:
1) Place 50rm into /system/etc/init.d via Root Explorer (shouldn't make any difference)
2) Change permissions on 50rm.
3) Doublecheck the permissions.
4) Create and configure custom_backup_list.txt
5) Reflash the same ROM (I'm using custom MTD - however, that also shouldn't change anything)
6) Verify visually that the script didn't work.
7) Verify that 50rm is in place with correct permissions.
8) Reboot and adb logcat...

I just did step 5 and my phone goes to splash screen, reboots from splash screen, fully boots in density 220.
Code:
adb shell grep ro.sf.lcd_density /system/build.prop
ro.sf.lcd_density=220
How did you create your script? When I just created it using notepad for windows, I get the Exit Code 111 and no LCD Density change.
Creating with notepad ++, script runs fine and LCD density gets changed correctly.

if you have to move directory i think that you have to do: mv -v -t source dest
cause -t is used for specified that you want move a dir and -v to show what the command are doing....
for the ln command use this format: ln -s /my/existing/directory thisismylink
...and i see that you wrote "1n" and not "ln" but maybe is a paste error

I want to introduce a new android project - Entware. It can be considered as an Optware replacement.
Entware (arm version for cortex-a9 or higher) was first done for routers
_cannot post url ((((
Later it was tested on NASes
_cannot post url ((((
It is based on another project Qnapware, that is based on Entware (mipsel version).
Today I've tested Entware.arm on android (routed RK3188 TV stick) and it works.
I'm rather new to android. So my instuctions given below may not always be correct. I was installing Entware.arm connecting to android host using SshDroid.
1. I need a writeble /opt folder. I've done the following
Code:
/system/bin/mount -o rw,remount /
mkdir /opt
/system/bin/mount -o ro,remount /
I have a ext2 formated external sd card (symlinks are needed). I have made a directory and mount binded it to opt
Code:
mkdir /mnt/external_sd/entware.arm
mount -o bind /mnt/external_sd/entware.arm /opt
I do not know why android does not have shell in /bin
So let's make one
Code:
/system/bin/mount -o rw,remount /
mkdir /bin
ln -s /system/bin/sh /bin/sh
/system/bin/mount -o ro,remount /
Now I'll need a local root profile with the content to execute global Entware profile:
Code:
[email protected]:/data/data/berserker.android.apps.sshdroid/home # pwd
/data/data/berserker.android.apps.sshdroid/home
[email protected]:/data/data/berserker.android.apps.sshdroid/home # cat .profile
#!/system/bin/sh
. /opt/etc/profile
The preparation is finished. Now let install Entware
Code:
wget h__p_//qnapware.zyxmon.org/binaries-armv7/installer/entware_install_arm.sh
chmod +x ./entware_install_arm.sh
./entware_install_arm.sh
After the installation - logout and login again (to execute /opt/etc/profile) and install packages
Code:
opkg install mc
If something in my instructions does not fit android philosophy - please inform me.
Addition:
To make Entware changes permanent we needs startup script. Something like
Code:
#!/system/bin/sh
sleep 3
/system/bin/mount -o rw,remount /
sleep 1
/system/bin/chmod 777 /mnt/external_sd
/system/bin/mkdir /opt
/system/bin/mkdir /bin
ln -s /system/bin/sh /bin/sh
/system/bin/mount -o ro,remount /
sleep 3
/system/bin/mount -t ext2 -o rw /dev/block/mmcblk0p1 /mnt/external_sd
/system/bin/mount -o bind /mnt/external_sd/entware.arm /opt
sleep 2
/opt/etc/init.d/rc.unslung start
This script creates /bin /opt folders creates symlink /bin/sh, binds /opt to Entware folder location and starts Entware services.

I want to introduce a new android project - Entware. It can be considered as an Optware replacement.
Entware (arm version for cortex-a9 or higher) was first done for routers

Later it was tested on NASes

Interesting.
Is this for smart phones???

Entware will work on armv7l/cortex-a9 or compatible CPU. It does not matter, weather it is smart phone, tablet, router or NAS.
Working well on this end, except for the fact that it has no concept of Android users and groups. For example, ls -l from busybox returns things like user "1000" group "1000", and bash with a PS1 including \u returns "I have no name!". Thoughts?

Hi,
I've tried a lot of things now, but I'am failing at editing a file in android /sys folder. I want to change a variable for battery charging in /sys/class/power_supply/battery/batt_tune_float_voltage. In a terminal I've performed following
Code:
1|herolte:/sys/class/power_supply/battery # cat batt_tune_float_voltage
43500
herolte:/sys/class/power_supply/battery # chmod 777 batt_tune_float_voltage
herolte:/sys/class/power_supply/battery # echo 42000 > batt_tune_float_voltage
1|herolte:/sys/class/power_supply/battery # cat batt_tune_float_voltage
43500
I even cannot mount battery_tune_float_voltage
Code:
1|herolte:/sys/class/power_supply/battery # mount -o rw,remount /sys
herolte:/sys/class/power_supply/battery # mount -o rw,remount batt_tune_float_voltage
mount: 'batt_tune_float_voltage' not in /proc/mounts
Does anyone know what the problem here is?! I would be really glad if someone could explain me if i've missed something or why this does not work.
Anyway: As I'am understanding so far, the App Battery Charge Limit here on xda uses following code for editing file /sys/class/power_supply/battery/batt_slate_mode
Code Link
Code:
val switchCommands = arrayOf("mount -o rw,remount $file", "echo \"$newState\" > $file")
if (alwaysWrite) {
suShell.addCommand(switchCommands)
} else {
suShell.addCommand("cat $file", 0) { _, _, output ->
if (output[0] != newState) {
setChangePending()
suShell.addCommand(switchCommands)
}
}
}
}
