SUSE 10 startup script

[DylanMuir]

Hi,

Here is a startup script for SUSE 10 which works nicely for me. The script tests for the existence of the config file and binary. Debug level and music root are specified as vars in the script. since I have my music on a slow-ish firewire drive, sometimes it’s not visible when the machine boots; this script waits for the specified music directory to appear before running mt-daapd.

The script behaves nicely with respect to stop / start commands and return values.

Nice. I’ll put that in contrib. Thanks.

Within the ‘start’ block I added a timeout in case the drive never mounts:

MaxTries=120

count=0;

## Wait for the music cache to appear

while [ ! -e $MUSIC_WATCH_DIR -a $count -lt $MaxTries ]

do

echo  "mt-daapd: Waiting for music directory to appear..."

count=$((count+1))

sleep 1

done



if [ ! -e $MUSIC_WATCH_DIR ]; then

echo 'mt-daapd: ERROR: unable to see music directory'

exit 1

fi

Unfortunately, my USB drives don’t show up until sometime later. Any suggestions as to what could be added to the ‘Required-Start’ block to cause this init to run later?

Thanks,

Michael
