Guest 1of2 Posted May 14, 2010 Report Share Posted May 14, 2010 (edited) Ho all, I've rooted my desire with r3 and all is well, however I still have a few questions (I'm a noob on Android) I have partitioned 14G mounted @ /system/sd (ext3) and 1.5G mounted /sdcard (vfat) Ideally, I'd like to get rid of vfat altogether and just have single ext3/4 partition and bind mount /sdcard to /system/sd/sdcard, bhut that is the future, For now, I'm trying to figure out how I can add the following two commands to the start up init. mount /system/sd/music /sdcard/mp3 -o bind mount /system/sd/photos /sdcard/dcim -o bind I want the default apps (music player and camera to access the larger partition and not the vfat). Also, somewhere during bootup (before /sdcard is mounted), the system does an fsck -t vfat /sdcard (actually the /dev/ name), we need to add fsck -t ext3 to the /dev/block/mmcblk0p2 because if you lose power, you can corrupt the ext3 fs and fsck must be performed the phone will not boot. Anyone know were this is mounted from ? Thanks. Albert. Edited May 14, 2010 by 1of2 Link to comment Share on other sites More sharing options...

Guest ddvo Posted December 11, 2010 Report Share Posted December 11, 2010 (edited) This is how to got automounting an ext3 data partition on the SD card to work on my HTC Desire running 2.2 (Froyo). I formatted the card with a tiny (50 MB), essentially unused, vfat partition - just in case Froyo insists in finding/mounting it - and all the rest with a single large ext3 (or ext2 or ext4) partition. I use the latter partition flexibly both for data (in a directory "/card", which I bind mount to "/sdcard" as described below) and for app storage (in directories "/app", "/app-private", and "/dalvik-cache", which are sym-linked from "/data/app" etc. using "/etc/init.d/02stuff2sd" - attached -, which is some older version of http://pastebin.com/8LJj8rVz). Since the /etc/init.d/02stuff2sd script already mounts at boot time the ext3 partition to /system/sd, I just added a second script as /etc/init.d/20autostart, which essentially bind mounts the "/system/sd/card" directory of the ext3 partition to the /sdcard directory: busybox mount -o bind /system/sd/card /sdcard Optionally, one may remount the "/sdcard" directory with stricter security settings: busybox mount -o remount,nosuid,nodev,noexec,rw,errors=remount-ro,dirsync,relatime /mnt/sdcard where unfortunately it is not possible to give the following extra parameters, which would give uniform access rights to all files: uid=1000,gid=1015,fmask=0113,dmask=0002,allow_utime=0020 It turned out that that android.process.media (app_21) messes with the access rights of the photos taken by com.android.camera (app_42) and stored as /sdcard/DCIM/100MEDIA/IMAG0001.jpg etc., which does not surface when DCIM is part of the vfat partition because there is essentially no access right restrictions. As a workaround for the ext3 partition, to prevent errors like "no photos or videos found", my boot script additionally does chmod 666 /sdcard/DCIM/*/* One caveat: after unmounting the SD card directory /sdcard, mounting it again via the regular Froyo user menu results in the vfat partition being mounted instead of /system/sd/card . So either you need to mount it manually via the terminal emulator (or via adb), or simply re-boot.02stuff2sd.txt Edited December 11, 2010 by ddvo Link to comment Share on other sites More sharing options...
