The MythTV overlay is not serviced by layman. Instead, it includes a
script called from /etc/portage/postsync.d/ to update itself after every
emerge --sync.

Now that you understand how it works, I hope you can see that your
comments still make absolute sense.

Basically, there are two types of portage tree, ones you manage yourself
and one that are managed remotely and synced to your system. The latter
includes the main portage tree, all layman overlays and the MythTV one.
Only fiddle with the former.

Much clearer now, thanks to you and Alan. I'll try to do it the proper
way.
