Beldin,

With previous upgrades (had my N800 tripple booting; internal, ext p2 2007, ext p3 2008 and N810 through original 2008 to the first, and now, second Diablo), I found the rebuild went pretty quick. Not sure if it helps any but here's how I cut the card up:

p1, fat32 - 6 gig - general storage of all personal data file, images, music.. anything that would fall under the various document folders off your /home/user plus maemo mapper data since the GPS was a primary reason for my upgrading to the N810. Now I can fit the complete 2.3 gigs worth of HOPE2008 talks in high quality on there without removing anything else to make room.

p2, ext2 - 1.5 gig - cloned install plus everything I'm going to be reinstalling over the next few days. In my /home/user I keep only the various config files that get dumped there. I have a few personal scripts stored in /home/user/bin and some other non-maemo binary apps in respective directories under /home/user/lib. Other than those two additional directories, only what has to go under my home directory goes here. Anything else I can store outside of /home/user goes to applicable directories under the fat32 partition 1.

Internal SD remains reserved for the maximized swap file and Maps related data which ships with the N810.

Internal Flash remains reserved as a factory+updates fresh build and "SystemRescue" for the exact type of issues that led me to post here originally.

It may make your rebuilding a little more present if you've not already got a similar setup.

(gah.. I have my pocket pentest box and PDA back. Damn that was a long week blocked from all my GPE data.)
