letting glabel recognise a media change

hi there,

i wanted to ask if it would be possible to asjust glabel so that e.g. inserting
a new media into a dvd-drive gets recognised and glabel displays the lablel
right away.

right now i use this shell alias to work around this issue:

mdvd='sh -c ": 3>/dev/dvd" ; mount /media/dvd/ && cd /media/dvd/'

cheers.
alex
