Reflashing & Restore

this is a slightly modified version of the script I use to restore my N900 after a reflash. My reflashing procedure is:

• use Backup and store everything on SD card
• reflash with standard http://wiki.maemo.org/Updating_the_firmware, i.e.

sudo flasher-3.5 -F RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin -f -R

• restore old backup except programs
• install gainroot
• in Terminal:

 sudo su -
/home/backup/restore

with following script in /home/backup (feedback and patches are welcome). It excepts that did a backup of /root and your selected modified files (e.g. /etc/ssh) in /home/backup. the file minimal should contain a list (line by line) of the package names you want to install.
