The patch below makes /etc/init.d/mpd start the MusicPlayerDaemon in
a more normal way:
1- it stops it from rebuilding the database at every start (which can take
a very very long time on large databases).
2- it stops it from going through the trouble to create the music
database directory (even if it exists, as long as its empty you won't
be able to do much with it anyway).
3- it stops it from messing up the playlist (adding all the songs in the
universe to it) and from starting to play that messed up list
forcefully right away (convenient when your machine happens to reboot
at 3am).
4- it uses `nice' if available to boost `mpd's priority to reduce the
likelihood of skipping. In my experience (using this mpd on a small
home-router box), this is indispensible to avoid skipping, and I have
never noticed it affecting the general performance and responsiveness
of the machine.
Points 1 and 3 are really important for most normal uses I can think of.
Point 2 is not important.
Point 4 is important for my use case, tho maybe less so for others;
Still, within the context of OpenWRT, I expect it's common to run on
slow machines where "nice" is necessary to avoid skipping, so I think it
deserves to be used by default.
