This is a bit short-sighted. Using this doesn't allow you to install any 
additional packages (unless the package and its dependencies happen to be in the 
category of a package you already have installed) and will break dep resolution 
when the dependencies change for any packages that you currently have installed.

This is true, anyway I'm using it on all production servers with stable and
final set of packages.

I agree.  Why not just use an NFS mounted PORTDIR?

Re: [gentoo-server] trim down portage directory

[gibbonsr-ml]

I use a combination of the suggested on my Servers.  I use a a NFS mounted portdir, 
and my exclude list is just a lit of all the KDE-*, gnome-*, xfce-*, and x11-*.

I don't use X so it seems to work pretty well, and it still keeps the re-cache time
to a minimal.

and what about way back. If you need to migrate host on desktop?

Just remove the excludes file (or replace it with an empty file to keep
rsync happy), and things will be back to normal upon your next sync.

cheers,
