$ cat /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local



as ROOT added following line to this file

chmod 666 /dev/sg1


Rebooted the PC then it worked as ROOT only but not as USER

as USER
# ls -l /dev/sg1
crw-------    1 satimis  root      21,   1 Apr 11  2002 /dev/sg1

Still have to issue

# chmod -c 0666 /dev/sg1

to make it works


B.Regards
Stephen
