in any event, since I couldn't turn it on, I couldn't reflash it. and yes I tried leaving it out overnight with and without the battery.
As for installing initfs with bootmenu
You can still skip the final flashing part and download created initfs.bootmenu.jffs2 image (and initfs.orig.jffs2 backup) to PC and flash via official flasher if you want to be extra safe.

there is no menu and only first found ext2 partition is used. When I created bootmenu, initfs could boot only from mmcblk0p1 which was not very useful for running cloned system.

Later they added search_root_onmmc() which scans all mmc partitions for executable /sbin/init and first one is booted.

I'd love to see some sample scripts to accomplish this. I want to implement a similar backup system using rsync.

I set my home router to always issue the IT the same IP every time it connects via WiFi (also makes things easier to connect to for other things). Each night the script pings the IT and if it's online will SSH to it and backup securely via rsync, this backs up the entire tablet including any cards loaded.
I also added a few more things, using hard links on my backup box I can keep weeks of backups using a fraction of the space and if the IT is offline for more than 10 days then I get an e-mail each night until it gets backed up

Code:
/usr/bin/rsync --bwlimit=512 -az --log-format=%f --numeric-ids --delete --rsh=ssh --stats --exclude-from=/backup/scripts/libs/host.example.com.exclude --link-dest=/backup/backups/host.example.com/2008-03-05-01 host.example.com:/ /backup/backups/host.example.com/2008-03-06-01
)All the scripting is just the checking that commands executed correctly and building up the above command.
I hope that helps.

so, I think doing daily rsyncs and compiling them to a flashable image is probably the best overall backup solution. can anyone point me to a reference on how to do this?
also, does anyone have any further information on booting from SD using the stock init.fs as fanoush noted? I'm curious what the limitations are.
