Re: [gentoo-user] Gentoo Machine Cleanup

[Samir Faci]

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.
