[gentoo-dev] Reserve mythtv user UID 103

[The Bit Pit]

Howdy,

I'm a Proxy Maintainer in training.

I'd like to reserve a user mythtv for media-tv/mythtv. It is used for a daemon 
server mythbackend.

I selected UID 103 since my system used it before digital ATSC signals were 
available in the USA.
