Duplicating gentoo packages to a new machine

varnit — Wed, 24 Oct 2007 21:15:54 +0000

Simply copy /var/lib/portage/world from the old machine to the new one.
Then:

# emerge -va –noreplace $(cat old_world_file)

This command will install all of the files in the old_world_file while also adding them to the world of the new machine. The –noreplace was added in case some packages had already been installed, in order to avoid repeating one’s self.

Restore deleted ._cfg files

varnit — Wed, 24 Oct 2007 21:09:53 +0000

With –noconfmem, portage will “forget” that it has already made a ._cfg file for a CONFIG_PROTECT file, thus causing portage to reinstall the ._cfg file needed for updating.
