I'm using some custom made gentoo setup, it's not perfect but works fine for
me (>30 gentoo servers and >50 gentoo vservers in different locations)
Every gentoo server has mounted snapshot of portage tree compressed by
squashfs = 40MB (vservers are using bind mounted version), it's extended by
custom overlays (security, updates, etc). I can do 'big' upgrade of gentoo by
putting newer portage snapshot.
I've made custom gentoo profiles (f.e. amd64-default-20061004) which are
setting most things like cflags, use flags, overlays and inherits real
profile at the end. Also I'm extending it by creating my subprofiles to force
installing packages, for example:
x86-default-20061004/h (vserver hardware node)
vserver-default-20061004/www/php5 (www vservers with php5)
vserver-default-20061004/mail (mail vservers)
Most servers/vservers have /var/lib/portage/world empty, all packages are
forced by putting it into 'system'. Also, /etc/make.conf on all servers are
empty too :)
After emerge (compile) of package, it's sent into binhost server (via scp
in /etc/portage/bashrc) and other servers in same profile are fetching binary
version.
This solution is a little bit tricky, have some issues but after all - makes
many things faster and easier for me.
