Would it be possible to add 'yum autoremove -y'? Only CentOS 6 doesn't
have that command.

Otherwise looks good.

Is that so? The apt equivalent is usually pretty solid, and as
I mention in the commit message getting rid of obsolete packages can
really help when upgrading fast-moving targets.

I'm also not *that* worried about potentially breaking builders to
be honest, since with our current level of automation the worst case
scenario is spending around an hour rebuilding them from scratch :)

"yum autoremove" is a command for reliably screwing up your system and
should never be run without manual inspection of what it is going todo.

Good point, I must not have found out about it because I was
looking at CentOS 6 :) I'll post v2 in a bit.

[libvirt] [jenkins-ci PATCH] guests: Clean up packages after update

[Andrea Bolognani]

The package cache can grow to eat up a lot of disk space, and
not removing unused packages can lead to upgrade issues down
the line for fast moving distributions such as Fedora Rawhide.
