Description Ari Feinberg 2011-01-27 00:35:40 UTC
SELinux is preventing /usr/bin/mpd from 'read' accesses on the directory /home/mpd/music.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that mpd should be allowed read access on the music directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep mpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-01-27 11:23:02 UTC
We define in the policy

HOME_DIR/Music(/.*)?    gen_context(system_u:object_r:audio_home_t,s0)
HOME_DIR/Audio(/.*)?    gen_context(system_u:object_r:audio_home_t,s0)

If you mv it to ~/Audio or ~/Music and run restorecon on it, the MPD daemon
will be able to read it.

Or you need to setup the proper label for this directory.

# semanage fcontext -a -e /home/mpd/Music /home/mgrepl/music
# restorecon -Rv /home/mpd/music/
