From the ebuild of media-sound/mpd-0.11.5-r2:
ewarn "Home directory of user mpd, as well as default locations in mpd.conf
have"
ewarn "been changed to /var/lib/mpd, please bear that in mind while
updating."
ewarn "your mpd.conf file."
The mpd.conf is installed in /etc/mpd.conf, not /var/lib/mpd
And another small mistake: The period behind updating in the second line ;)
PS: Looks like mpd could be cleaned up a bit, there are still some 0.12.0 RC
ebuilds, whereas 0.12.(0|1) have been released and are in the tree
The message tells you that locations (paths) in /etc/mpd.conf have been changed
to /var/lib/mpd, i.e. music_directory points to /var/lib/mpd/music.
The extra full stop in 0.11.5-r2 has been removed, as well as rc ebuilds.
Thanks!
