Just noticed something a bit odd. I made a backup of my rootfs, my first since upgrading to PR1.3. I ubinized it etc on-device as before to generate a flashable image file. Now, I'm running a custom kernel (based on the latest BFS source, but with an extra diff patch to enable cache_file on nandsim module) and have used this, along with ubiattach, to mount the image file generated by ubinize to /mnt/rootfs. So far, so fairly mundane. However, df -h shows:
Now, admittedly it's a slightly bigger partition (mainly because it's 10000000h in size, rather than the normal 0fb40000h of the real rootfs) but why is the free space so much bigger, and would I gain this extra space should I flash the image? (I'll probably try later just to see, but I found this all really curious..)Code:Filesystem Size Used Available Use% Mounted on rootfs 227.9M 178.8M 44.9M 80% / ubi0:rootfs 227.9M 178.8M 44.9M 80% / ... ubi1_0 232.3M 161.1M 67.0M 71% /mnt/rootfs
If you didn't, you ended up with (essentially) a tar.gz file - the tar file sticks all the files together, then ubifs compresses it. Which explains the extra space... but it won't boot.

@RobbieThe1st: one more suggestion. Could you change the shortcut for either advanced menu or within there for the entry to erase all files from opt? As both shortcuts are 'e' it might be possible one is accidentally hitting 'e' twice and therefore erasing his opt-partition.
Maybe you can use an uppercase letter for advanced menu. So no one would accidentally even enter it.
As far as uppercase letters... I'm not sure. I'll have to see if I get any different codes when I hold down alt and another key at the same time.

I did extract the tar to a directory ext filesystem - /home/user/rootfs, not to MyDocs because as you say, the permissions would've been lost. I've got a script to "ubinize" the tar after extracting it, and looked at the mounted folder to confirm all the files and folders are there. I also didn't use compression when creating the backup. So, I'm still not sure where the extra space comes from - I even created partitions using nandsim so the layout is the same, and it gives me about 18MiB extra space, or 8%. Very weird.. I haven't tried to flash it yet though.

Works for me.
First install, version 0.56-1 on PR 1.3
Cheers.
Now if this could only be made to work with the
U-boot - Power kernel combo it would be over the top.

Here's a sed command for forcing the use of /bin/sh for root in /etc/passwd
Code:
cat passwd | sed -e 's/^\(root:.*:\)\(.*\)$/\1\/bin\/sh/'

Call would be
Code:
chsh -s <SHELLNAME> <USERNAME>
BTW: you can transform and copy passwd in one go using input/output redirecting:
Code:
sed ... < ORIGFILE > NEWFILE

Q: may it be, backupmenu is consuming a lot of power when backing up? I shut down device with battery at ~75%, made a backup and started again and battery was at 53%. I know, the charge reading ain't accurate at all but this difference is mentionable. Is there any way one can reduce the power consumption a bit?
