What do you mean exactly? I use minidlna on -current and have for about 6 months. I wrote a very amateurish script that actually kills the program and deletes the database before relaunching because the database wouldn't update no matter what, but rebuilds it just fine every time. I never Have a problem with my xbox seeing the minidlna server on the LAN. There is a static source versus the dynamically linked version available and I used makepkg to create a slackware package with it since it wouldn't build against the newer ffmpeg I have installed.
Code:
kill `pidof minidlna`
rm /var/cache/minidlna/files.db
sleep 5
minidlna
echo "minidlna now started"
