I tried your scripts today on my setup (in last post). First I commented out those lines checking kernel version and md5 checksum in M32Binit.sh and M32GBboot.sh to let the script work with PR1.3.
(Before running the scripts I uninstalled Backupmenu and bootmenu-n900 and had no other bootmenu packages installed.)
M32GBinit.sh runs fine and everything is in place under the new "/home".
One small issue came when I ran M32GBboot.sh. I opened it and found that it mainly has to do with copying /sbin/preinit and bootmenu.sh under /.
So first I changed "PR12" to "PR13" in the script and commented out the md5sum bit.
Then ran the script. At the end of the execution of the script it showed bootmenu.sh not found. But then I checked bootmenu.sh was copied there.
Rebooting I couldn't see boot menu and the original rootfs boot as if no dualboot setting had been installed.
I checked mount and df and found things were the same as before running the scripts.
Finally I copied back the original preinit and moved bootmenu.sh to somewhere else. Everything runs just fine. Nothing seemed to happen...
I attach the messages and my edited scripts here. Could you explain what happened? Thanks!
