Mounting the optfs isn't hard. I'm pretty sure it would be:
Code:
mount -o ro,loop -t ext3 /media/sdc1/SystemBackups/20101109-backup-optfs.img /tmp/n900
...As root.

Code:
knoppix@Microknoppix:~$ su root
root@Microknoppix:/home/knoppix# mkdir /tmp/n900
root@Microknoppix:/home/knoppix# mount -o ro,loop -t ext3 /media/sdc1/SystemBackups/20101109-backup-optfs.img /tmp/n900
mount: wrong fs type, bad option, bad superblock on /dev/loop/0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
Still problems.

Maybe I'll just quickly install ubuntu on a spare hdd when I get the chance.

Last I checked, nitdroid uses keyboard out boot and is thus incompatible with BM.

Yeah, i figured it out.
I mounted it on the n900 itself, and it worked fine.
thanks for all the help people

If you want to do something of the sort, all you would have to do is:
1. make an initrd with all the files listed in /usr/share/backupmenu/BackupMenuLauncher.item
2. run /usr/share/backupmenu/BackupMenu.item from inside the initrd as a shell-script with ash.

It's actually pretty easy to mess with, but I don't know an awful lot about initrd's and other boot stuff - It's GPL, though, so you can do it yourself.
I have done some research and now I am skilled enough to (or try to) prepare an initrd for N900.

So I can try to make an Initrd image with backupmenu, but unfortunately there is a main problem to resolve.

N900's kernels haven't ext2 or ext3 statically compiled so the only filesystems available at boottime are ubifs and cramfs

Ubifs cannot be used for a ramdisk and cramfs in read only but I have read that Backupmenu wants a RW filesystem.

No, there shouldn't be any need for a RW filesystem, though the launcher script will/does(I forget if it's in the latest, or just the version I'm working on) include a tarball of script files which get extracted at runtime. Obviously, provided that those script files are in place when BackupMenu.item gets run, everything will be fine.

Oh, there -are- a couple of files in /tmp/ that get written too(status files) - You'd want to mount a tmpfs there before running BackupMenu.item
Note that that's not hard, and tmpfs support -does- seem to be compiled in.

As parallel project I spent the last 2 days learning well BootMenu and Multiboot with intention to port BackupMenu under Multiboot also.

Today I have discovered that someone other has already done it and he have already published a complete guide.

ups sorry i dont see your post.

thanks for doing it.

i am searching some solution to this.

it would be best to create a separate installation from the repositories do not need bootmenu and that it was compatible with multiboot.

backupmenu've tried so far and is working perfectly but I have problems with kernel-power.
