DOES NOT WORK ON CUPCAKE 1.5. Try one of the other apps to sd card threads.
I decided to create a new thread for hacking a rooted g1 to allow applications to run from the sdcard. The original thread's instructions don't work without some modifications and the original poster doesn't seem to have the time to update it.
I'll try to keep the original post as up to date as possible as new information comes.
Prerequisites:
1. Rooted g1 with jesus freak version 1.30 or 1.31, 1.41 (rc30, rc33) Works with all rooted US, UK, international versions of the g1.
2. Have "adb" from the android sdk installed on your desktop machine.
Sdcard preparation:
Divide your sdcard into 2 partitions. The first partition should be FAT, the second partition should be EXT2. This can be most easily accomplished using a linux or mac machine. For windows, you can use "paragon partition manager 9" to do this. It will allow you to partition your sdcard and format the 2nd partition to ext2 fs. It is very important that the 2nd partition be formatted as EXT2 or the rest of the procedure will NOT work. The 2nd ext2 partition will be used to store your installed apps.
In the original thread, somebody mentioned a HP sdcard partition tool program, but I don't believe that will allow you to format the partition to EXT2 fs.
Procedure:
1. With the phone off, insert your newly partitioned sdcard into the g1.
2. Connect your g1 to your desktop via the usb cable and turn it on.
3. Backup your original mountd.conf and initrc.rc files from your g1 by running the following commands on your desktop from the cmd shell:
adb pull /system/etc/mountd.conf <dir on your desktop>
adb pull /system/init.rc <dir on your desktop>
4. Mount your g1's /system directory as writable via the desktop cmd shell:
adb remount
5. IMPORTANT! Create a /system/sd directory on your g1 via the desktop cmd shell:
adb shell mkdir /system/sd
adb shell ls /system and make sure that the directory has been created.
6. Download the attached modified mountd.conf and init.rc files to your PC.
7. Push the modified mountd.conf to your g1 via the desktop cmd shell:
adb push /<dir on your desktop of modified file>/mountd.conf /system/etc/mountd.conf
8. Push the modified init.rc to your g1 via the desktop cmd shell:
adb push /<dir on your desktop of modified file>/init.rc /system/init.rc
9. Reboot your g1
10. Connect to the g1 shell via the desktop cmd shell:
adb remount
adb shell
11. Check to see that the ext2 partition has been created and mounted:
busybox df -h
You should see a line that looks similar to this:
/dev/mmcblk0p2 1.2G 9.1M 1.1G 1% /system/sd
If you don't see this line, you didn't partition your sdcard correctly. STOP! Go back and do that.
12. From the G1 shell run the following cmds to copy your app and app-private directories from the internal g1 storage to the sdcard.
busybox cp -a /data/app /system/sd
rm -r /data/app
ln -s /system/sd/app /data/app
busybox cp -a /data/app-private /system/sd/app-private
rm -r /data/app-private
ln -s /system/sd/app-private /data/app-private
13. Reboot, enjoy all the extra storage!

Dunno if this has been posted yet, but the undo process is simple. I just did it with no problems, and thought others might want it as well. (Note-if you're copy pasting this to do it, anything following # til the end of a line is just a comment, don't copy/paste it.)
adb remount #makes your file system writeable
adb push /<place you backed up mount.conf to>/filenameofbackeduporiginalmount.conf /system/etc/mountd.conf #restores the original mount.conf

Instructions without adb using terminal app by LucidREM
this is a form of the instructions from this thread .. but modified slightly to be used directly from the "Terminal" .. i did not use my USB on my phone to root or run apps .. everything i did was on the G1
$su
#mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
#mkdir /system/sd
6. Download the attached modified mountd.conf and init.rc files to your SD.
#busybox cp -a /sdcard/mountd.conf /system/etc/mountd.conf
#busybox cp -a /sdcard/init.rc /system/init.rc
9. Reboot your g1
$su
#mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
#busybox df -h
You should see a line that looks similar to this:
/dev/mmcblk0p2 1.2G 9.1M 1.1G 1% /system/sd
If you don't see this line, you didn't partition your sdcard correctly. STOP! Go back and do that.
12. From the G1 shell run the following cmds to copy your app and app-private directories from the internal g1 storage to the sdcard.
#busybox cp -a /data/app /system/sd
#rm -r /data/app
#ln -s /system/sd/app /data/app
#busybox cp -a /data/app-private /system/sd
#rm -r /data/app-private
#ln -s /system/sd/app-private /data/app-private
Reboot your g1
Update 1/19/2009:
Installing non-wipe custom themes shouldn't cause any issues. I just installed the BUUF theme and I didn't have to re-do the procedure.
Update 1/20/2009:
Added undo procedure by heldc
Update 1/27/2009:
Added procedure for moving data directory to the sdcard, without performance issues.
This is not stable so I've moved it to the bottom.
13. Copy /data/data directory from internal storage to sdcard. This is OPTIONAL as some people are still reporting issues.
mkdir /system/sd/data
cp -rp /data/data /system/sd
rm -r /data/data
ln -s /system/sd/data /data/data
Reversal procedure:
rm /data/data
cp -rp /system/sd/data /data
Update 2/7/2009:
Add instructions by lucidrem that doesn't require adb. Allows you to apply the hack from the g1 using terminal app
going to try this right now..i will tell you if it works on my G1
i followed all the steps and i was able to boot into my phone without any problems. I was also able to install apps from market BUT when i instaled them my STORAGE LEFT went down from 54 to 51MB.
**I can see all the apps i installed in /system/sd/apps
please help,
thanks
Running apps off the SD card show any signs off slowness or laggyness?
Hey I would like to know what software are u using to create the partition on the sd, I tried partition magic 8 and partition mananger but the softwares can't see the sd card.
I use Paragon Partition Manager 9

Only the apk files are moved to the sdcard. The apps database files are still on the internal storage and all the cache files are still on the internal storage. Its still a good idea to manually move them over to the sdcard.
So as you install more apps, the internal storage will still shrink, but not as much as before and will go down slowly.
You can try to also move the /data/data directory over to the sdcard, that will move all the database files from the internal storage to the sdcard, but I haven't tried that. If you have a class 6 sdcard, try it and see if that slows things down.

Now I have to figure out how to do the partition in Ubuntu Lol
hi,
i'm a total noob to this. I've managed to pull the mountd and init files to back them up. When I get to step 5: adb mkdir /system/sd when I press enter the cmd shell gives me the adb menu. How can I tell if the dir was created?
Thanks for any help you guys can give.
1) adb shell
2) mkdir /system/sd
thanks a lot.
For the person that asked how to partition your sd card in Ubuntu you can use partition editor under system-administration- partition editor

Thanks for the info but I just find out tha paragon partition mananger can creat ext2 partitions too
everything went right with the software it create my fat32 partition and the ext/2. what I don't know is if the ext/2 is formated and my computer with linux does not see sd card at all so right now I don't now how to confirm this.
ps. I try to look for the option SYSTEM THEN ADMITNISTRATION and it does not have the partition editor installed.

Try this and see if it works... I haven't tried it myself as I only have the stock sdcard and I know its going to be too slow.
adb shell
cp -a /data/data /system/sd
rm -r /data/data
ln -s /system/sd/data /data/data
reboot
If this doesn't work or its too slow, to reverse it do the following:
adb shell
busybox cp -a /system/sd/data /data/data
If this works well, I'll modify the original post...

ok.. strange that your internal storage is still at 52mb though.. something else must be eating it...
do this:
adb shell
busybox df -h
cd /data
ls -l
and post the results...
# busybox df -h
busybox df -h

How to explain that it is impossible to mount the system partition in recovery ? Should I format my sd card to correct that ?
the /system/ files do not reside in your sd card. They are stored in your phone. Are able to boot up your phone at all? If so you can mount it via a terminal app. You might also need busybox installed. At the terminal type the following
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock1 /system
Having encrypted /data, I'd been interested in encrypting the SD card, either in full, or a full partition. As a new poster to xda, posting without citing reference links does prove a bit more challenging, but here goes:
Given an HTC Sensation, rooted, with Cyanogenmod 9.1 (ICS), and Clockwork Recovery, I partitioned (thru Clockwork) the SD card into FAT32, ext, and swap. Your milage may vary on the next step, but using Fedora, I accessed the SD card, deleted the ext partition, and recreated as an encrypted partition, type ext4. (read up on cryptsetup for alternative ways to create this) For the sake of this post, we'll use the password, "ChangeMe".
I installed LUKS Manager from Google Play, which provides lm.cryptsetup, a renamed binary of Guardian Project's cryptsetup. I didn't use LUKS Manager's implementation of creating encrypted folders, instead, the whole sd-ext partition has been encrypted.
To mount the device at startup, I have the script 99sd-extLUKinit, located at /system/etc/init.d/
#!/system/bin/sh
# Not quite sure what these do, but kept them in
sync;
setprop lk.filesystem.ready 1;
# Remount the root file system to allow changes
mount -o remount,rw rootfs /
# Create the mount point and create a symbolic link
mkdir /mnt/sd-ext
ln -s /mnt/sd-ext /sd-ext
# Decrypt the SD card via cryptsetup, device resides on /dev/block/sd-ext
# Hopefully prompt user for password, but for now, echoed in
echo ChangeMe | lm.cryptsetup luksOpen /dev/block/mmcblk1p2 sd-ext
# Clean errors
e2fsck -y /dev/mapper/sd-ext
# Mount the SD Card via cryptsetup block device
mount -t ext4 -o noatime,nodiratime,barrier=1 /dev/mapper/sd-ext /mnt/sd-ext/
# Remount the root file system to prevent changes
mount -o remount,ro rootfs /
Once verified that the system will automount the encrypted ext4 /mnt/sd-ext partition:
ls /sd-ext
should return with lost & found directory
I moved /data/app and /data/app-private to the encrypted partition:
cp -a /data/app /sd-ext/app
rm -r /data/app
ln -s /sd-ext/app /data/app
cp -a /data/app-private /sd-ext/app-private
rm -r /data/app-private
ln -s /sd-ext/app-private /sd-ext/app-private
Any one can tell me what I make round. I have cyanogenmod with one sdcard with 2 partitions the first is mount with ext4 and the second I try fat32 ext4 ext3 ...
I no found fuse.ko in the system but internal partition and storage is mount with fuse in /storage/....
I try to mount the second partition by many difference ways . Always is mount and show up
I copy files from internal memory or sdcard first partition to the second partition
But if I try to open the files I got permission errors . Very possible is a Selinux problem but I have in permissive mode
I look with rootexplorer and files a copy in the 2nd partition in the sdcard for the owner only can read or write
Any ideas how to make the correct mounts for the 2nd Partition on SD card
I make a simple script for make test that is the last configuration I make but still only the owner can read or write that means any app can't open the files if is not root
that is the configuration I use
#!/system/bin/sh
# Mount SD Card Ext4 Script
mkdir /storage/sdcard2
mount -r -w -o exec,dev,suid,rw -t ext4 /dev/block/vold/179:66 /storage/sdcard2
mount -r -w -o exec,dev,suid,rw -t ext4 /dev/block/mmcblk1p2 /storage/sdcard2
chown media_rw:media_rw /storage/sdcard2
chmod g+w /storage/sdcard2
ln -s /storage/sdcard2 /mnt/media_rw/sdcard2
ln -s /storage/sdcard2 /mnt/sdcard2
chown media_rw:media_rw /mnt/sdcard2
chmod g+w /mnt/sdcard2
Hi there,
I'm sorry but I can't find anything related to your question.
Please post that in the forum bellow for more answers from the experts:

Good luck
Hello.
I just started messing around with my Z3 and so far followed the tutorial here https://forum.xda-developers.com/z3-compact/general/recovery-root-mm-575-lb-t3418714 to install root and recovery without unlocking the bootloader. Also took the chance to make a backup of the ta partition.
My objective was being able to mount an external ext4 partition so I could move game data and free some internal space. I believe the official kernel doesn't support init.d so I searched and found a script that worked and added it to the bottom of init.qcom.post_boot.sh.
Code:
### Init.d support ###
busybox run-parts /system/etc/init.d/
It's a very simple script that creates /sd-ext folder if it's missing and mounts /dev/block/mmcblk1p2 there
Code:
#!/system/bin/sh
#
# mounts ext partition from sd card
if [ ! -d /sd-ext ];
then
mount -o rw,remount /
install -m 774 -o 1000 -g 1000 -d /sd-ext
mount -o ro,remount /
fi
if [ ! -d /sd-ext ];
then
echo sd-ext not created >> /data/Test.log
else
mount -o rw -t ext4 /dev/block/mmcblk1p2 /sd-ext
fi
It was something that I got on some forum plus some trial and error and some Linux knowledge I have.
It seemed to work. The directory was created and mounted and I was able to move the games there using Titanium Backup.
But after I rebooted, the folder was there and all the data, but the apps don't show up on the apps list. I have to reinstall them...
Am I missing something? How can I fix this?
