Wondering if when you go with a Ubuntu Upgrade on a 4 gig SSD drive if it has the room for a Ubuntu dist-upgrade. I run AntiX / on my primary 4 gig SSD and /home on my secondary 16gig SSD on my EEEPC 900. I run as root in terminal
apt-get update && apt-get dist-upgrade
regularly on my 900 in AntiX since Wed May 04, 2011. I have to clean the cruft and jump through certain hoops to keep my 4 gig SSD install around 3 gigs
. Initial install of AntiX Full iso came in at about 2 gigs on a virgin install. AntiX is smaller than Ubuntu as far as I know. So even if you fix the password thing. I'll be curious if it does not fail when you do the upgrade and get a disk space error during it.
In case you want to try something different ,(Debian testing based, rolling release), though you probably are comfortable with Ubuntu and Gnome Desktop. Just throwing my instruction for installing AntiX at you.
