mpd will not install if /opt/local/var/lib/mpd/music is a symlink to my music

[bnilsson11]

After a successful installation of mpd, the easiest way to introduce the music library is replace /opt/local/var/lib/mpd/music with a symlink to your existing music library:

user $ cd /opt/local/var/lib/mpd
user $ ls -la
total 816
drwxrwxrwx 8 root admin 272 26 Sep 17:39 .
drwxr-xr-x 5 root admin 170 6 Nov 02:33 ..
-rw-r--r--@ 1 user admin 6148 22 Feb 2015 .DS_Store
-rwxrwxrwx 1 user admin 397023 16 Okt 22:43 database
drwxr-xr-x 4 user admin 136 22 Feb 2015 hide
lrwxr-xr-x 1 user admin 19 26 Sep 17:38 music -> /Volumes/htpc/Musik
lrwxr-xr-x 1 user admin 29 26 Sep 17:39 playlists -> /Volumes/htpc/Musik/Playlists

If mpd is upgraded or re-installed, the installation fails because "music" and "playlists" symlinks cannot be overwritten. I need to manually remove the symlinks and try again. After installation I need to replace music and playlists with symlinks again.

Life would be much easier if the installation/upgrade procedure would be more tolerant and check the status of these directories, and don't overwrite if they exist or if they are not writeable. The install/upgrade would then be more straight forward and transparent.
