devfs.conf & usb-thumbdrives

Hi,

I recently bought some Samsung USB-stick:
umass0: 0 USB DRIVE, rev 2.00/2.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: < USB DRIVE 2.00> Removable Direct Access SCSI-2 device
da0: 40.000MB/s transfers
da0: Attempt to query device size failed: UNIT ATTENTION, Not ready to 
ready change,


it 1 GB.

I created a devfs.conf-entry like this:
lbe# egrep da0 /etc/devfs.conf
perm    da0     770
perm    da0s1   770

but the permissions are still like this:
lbe# ll /dev/da0*
crw-r-----  1 root  operator   11, 112 29 Aug 23:13 /dev/da0
crw-r-----  1 root  operator   11, 115 30 Aug 00:15 /dev/da0s1

I first need to restart devfs:
lbe# /etc/rc.d/devfs restart
lbe# ll /dev/da0*
crwxrwx---  1 root  operator   11, 112 29 Aug 23:13 /dev/da0
crwxrwx---  1 root  operator   11, 115 29 Aug 23:13 /dev/da0s1


Why does it ignore these settings until a restart of the service?




cheers,
Rainer
