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... *** vinumconfig.c_dist Thu Dec 12 19:27:32 2002 --- vinumconfig.c Wed Jan 22 13:27:53 2003 *************** *** 1564,1571 **** vol->dev = make_dev(&vinum_cdevsw, VINUMRMINOR(volno, VINUM_VOLUME_TYPE), UID_ROOT, !
