System: FreeBSD mack.dcsl.Buffalo.EDU 5.0-RELEASE FreeBSD 5.0-RELEASE #1: Wed Jan 22 13:28:07 EST 2003 root@mack.dcsl.Buffalo.EDU:/usr/src/sys/i386/compile/MACK i386
>Description:
All disk devices are in group operator and group-readable so things
like Amanda can run as non-privileged users. The vinum driver
creates its /dev/vinum devices in group wheel with no group
readability permissions.
>How-To-Repeat:
Set up a vinum based volume, change the group ownership and permissions
manually, then reboot. Now that devfs is being used the changes
don't survive a reboot.
>Fix:
Patch attached below for file in /usr/src/sys/dev/vinum. It seemed
to work fine on my system...
