Hi,

i've some trouble with devfs and the permission on my SCSI-tape drive:

after a reboot the permissions on /dev/scsi/host0/bus0/target4/lun0 are as
follows
drwxr-xr-x 1 root root 0 Jan 1 1970 lun0/

A request on the tape-drive as normal user gives a permission denied and
the permissions on /dev/scsi/host0/bus0/target4/lun0 set to
drw------- 1 root root 0 Jan 1 1970 lun0/

all nodes in lun0 are having the right permissions:
ls -l /dev/scsi/host0/bus0/target4/lun0/

total 0
crw-rw---- 1 root tape 9, 0 Jan 1 1970 mt
crw-rw---- 1 root tape 9, 96 Jan 1 1970 mta
crw-rw---- 1 root tape 9, 224 Jan 1 1970 mtan
crw-rw---- 1 root tape 9, 32 Jan 1 1970 mtl
crw-rw---- 1 root tape 9, 160 Jan 1 1970 mtln
crw-rw---- 1 root tape 9, 64 Jan 1 1970 mtm
crw-rw---- 1 root tape 9, 192 Jan 1 1970 mtmn
crw-rw---- 1 root tape 9, 128 Jan 1 1970 mtn

So to get the whole thing work i need on /dev/scsi/host0/bus0/target4/lun0
the following permissions:
drwxrwx--- 1 root tape 0 Jan 1 1970 lun0

How could i reach this?? I tried using CFUNCTION

CREATE nst0 CFUNCTION GLOBAL chmod ${mntpnt}/scsi/host0/bus0/target4/lun0 770
CREATE nst0 CFUNCTION GLOBAL chown ${mntpnt}/scsi/host0/bus0/target4/lun0 0 26

but no work. Setiing the permissions by hand and activatinfg saving and restoring the state is also not working.
