Har du kigget på om det er en log-fil, der får disken til at starte igen?
Er der nogen grund til, at du har cron, sendmail og syslogd kørende på
jukebox'en?
Med fast ip kan du droppe dhcp klienten.
Derudover kan du lave et setup, hvor alt eyecandy og jukebox program
kører på serveren og streamer lyden over nettet vha nas.
