Why are you using a custom Perl script for this instead of the built in tools for this? Below is how I have it setup on my system... In /etc/devfs.rules... [localrules=10] add path 'da*s*' mode 0660 group 5001 In /etc/rc.conf... devfs_system_ruleset="localrules" In /etc/sysctl.conf... vfs.usermount=1 And what group 5001 is... [kitsune@vixen42]/etc> getent group 5001 devDAaccess:*:5001:kitsune [kitsune@vixen42]/etc> Allows the group "devDAaccess" to access /dev/da*s* and mount it. For more reading on this, I suggest the following man files... devfs.rules(5) rc.conf(5) devfs(8) _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
