I have modified the backupmenu 0.65 files in order to allow optfs formatting instead than erasing.

Thing is, when optfs is seriously damaged, erasing all files and directories like before might be insufficient to repair the filesystem.

This was an itch I really needed to scratch, because this way my N900 is much more independent from an external device in case the optfs gets messed up (an issue that happens quite often, unfortunately, at least in my hands, with all that fiddling plus an OC'd processor).

Of course, after formatting is done, you'll have to restore your (rootfs and) optfs.

The modded files in the attached tar.gz archive are BackupMenu.item and extrafiles.tar.gz and should be copied (as root) inside /usr/share/backupmenu - but you better rename the original files before, instead that overwriting, so that the pristine functionality can be restored if for any reason my mod doesn't work on your device.

Of course, before you test that, also do a full rootfs and optfs backup, in case everything gets messed up. I tested it twice and it always formatted optfs as expected, and the optfs tar file could be correctly restored.

Please RobbieThe1st consider including this mod in your next version; I don't think it's more dangerous than erasing all optfs files like was before, and it's more useful, at least imho.

Any reason this would not be done with root as well?

You mean unmounting optfs as root, while normally running the device, and formatting? It seems quite difficult to do, you'll find open files preventing you from unmounting.

That could be tried closing a number of processess, maybe, if watchdogs allow that, but using backupmenu the thing is much easier, and you will be able to restore from your tarred optfs immediately after formatting.

Right, it is useful as well. Let's go and see where it must be done.

Ah, while looking at the code, here's a typo:

Code:

#Restore the RootFS from $backupRootFile
mount -t ubifs ubi0_0 /tmp/mnt/rootfs
if [ $? -ne 0 ]; then
   umount -t ubufs
   $T2S -s 2 -H left -y $y -T 0xF800 -t "  Error: cannot mount the RootFS."; y=$((y+20))
pressAnyKey
break

Should be "umount -t ubifs" I bet.

Then after a few lines he writes:

Code:

$T2S -s 2 -H left -y $y -T 0 -t "  Clearing the RootFS..."; y=$((y+20))
  busybox rm -rf /tmp/mnt/rootfs/*

Here he nukes the rootfs' files. Formatting should replace the "busybox rm" line.

Anybody knows the right way to go? I'm scared to mess with ubifs, I haven't quite understood how it works

EDIT: is it "ubiformat /dev/whatever"?
and [Q] Why do you want to format rootfs just before restoring instead that having an extra command to do that? [A] Because if user formats rootfs with that command and forgets to restore a rootfs tar immediately after, will be left with an unbootable device that has necessarily to be reflashed.
