Didn't know about 'udevadm control --reload-rules', which might be
better in some situations.
I've presently got a problem where 'eject -T'
stops working after formatting a DVD/RW. A 'udevadm trigger' gets it
working again. (From the messages etc. my initial guess is something to
do with arrangement of the symlinks, e.g. /dev/sdb being the device,
'eject -T' expects /dev/cdrom 'dvdrw-tools expects /dev/dvdrw)
'udevadm trigger' fixes it \o/ , but seems to mess with usb mounting :(
although it's just band aid 'udevadm control --reload-rules' might be
the one for (re)adjusting the device symlinks and shouldn't mess with
"mtab behaviour"
