/home on SD and OpenZaurus 3.5.1, (Or anything newer than 3.3.5) Options

[darac]

Does anyone here use an SD card as their home directory under the new OZ3.5.1 or even 3.3.6pre1?

If so, how stable is it?

I'm really pleased with my 3.3.5 with the above configuration, but the one annoying thing is that the SD module doesn't seem to like suspending. This means that every time I want to turn the Z off, I've got to halt it.

If one of the newer versions has a better SD module, then I think I'll be switching over proto :-)

Hi,

I just installed /home /opt /root on my 256MB Lexus SD card and is working like a charm.

I'm beginning to get the feeling that the problem with sd cards not liking to suspend is more a problem with the cards than any ROM/driver issue. I have now tries OZ 64/0, crow 64/0, and tkcROM 64/0 all with home on sd. and every ROM requires reboot after resume. I just didn't want to blame my SD card cuz Lexar has high repute here. But then again home on sd may be more demanding than just extra storage...

I had the suspend issues with a total root on SD card. I used a script the moves everything to SD while mounted with option sync. It takes along time to do that, but .. Now I can suspend and resume with out issues most of the time. Once in a awhile .. my wifi card with hang up, and I will have to do a hard boot with the battery switch.

I will find the link to the the script for you later today.

Try that out. Like I said ... its working great for me, but this is a total SD setup not just home. I can still remove my SD card and boot from the NVram.

[ciffus]

After following these directions I am still unable to boot off of my sd card.
If I run the pivot root manually after booting up, I am unable to run any of the apps.

Any ideas of where to look?

Did run the script from your NVram root ? if you did it right you should have this in /sbin

CODE

/mnt/root/sbin#ls -l init*
