I'm actually trying a slightly different approach that's almost equivalent to doing a fresh install.
If I don't bork this up, I'll write a lil wiki on how to do this. 1. create a loopback file system. dd if=/dev/zero of=baseimage bs=1k count=5242880 (5 gig image) 2. partition the baseimage 3. do your typical gentoo install on the baseimage file 4. sync data from baseimage fs, to / omitting /dev /proc /sys /home making sure this is all backed up 5. rerun grub to make sure everything is proper 6. reboot and pray. so, if I'm right, that should give me a clean fresh install. I'll take a backup of my /etc directory and I need to remember to backup mysql db, but I believe that should work fine. I would do this off a liveCD if I had physical access to the machine. It seems like the cleanest solution. if I run emerge -uDN (etc) world it just keeps pulling X and other crap I removed, and since 80% of what's on the machine it unneeded, a fresh start wouldn't hurt. if anyone is interested, I'll post an update on how my install went once it's back up. -- Samir On 7/17/07, Abraham Marín Pérez <[EMAIL PROTECTED]> wrote:

This way you'll update only what you'll keep. Needless to say, it's always a good idea to back-up your system before proceeding. HTH, Abraham -- -- [EMAIL PROTECTED] mailing list
