Encrypted partition auto-mounted at boot above /home/user.
Default boot into the normal /home/user if no password is entered at the beginning of boot, when the blue led lits for 2 seconds.
Encrypted but connected...well, you know... technique sometimes lives for technique...

swap (not encrypted) on sd.

Backupmenu and auto.rsync from the PC

Cloned to a spare n900 with automatic wifi update

I Would change to Pro1 with Leste or SFOS. But: do I really need it? Have to try SFOS first.

I would advise you to begin with the reading of https://wiki.maemo.org/CSSU, and use backupmenu to when your installation is satisfying.
