Because there have to be certain permissions in order to allow a non-root user perform such tasks: 1. The setting vfs.usermount=1 has to be present in /etc/sysctl.conf . 2. The user must have write access to the device file. 3. The user has to own the mount directory. It helps if the user is in the "wheel" group. > 1. % mount_cd9660 /dev/cd0 /cdrom > mount_cd9660: /dev/cd0: Operation not permitted Check permissions of /dev/cd0 and /cdrom. > 2. % qemu-system-x86_64 -hda /dev/ada2 > qemu-system-x86_64: -hda /dev/ada2: could not open disk image /dev/ada2: > Operation not permitted Check permissions of /dev/ada2, maybe write permission is needed? > *SETTINGS:* > % id => uid=1001(xyz) gid=0(wheel) groups=0(wheel),5(operator),1001(xyz) > > /etc/devfs.rules has: [localrules=10] > add path 'ada[0-9]*' mode 0660 group operator > add path 'da[0-9]*' mode 0660 group operator > add path 'cd[0-9]*' mode 0660 group operator > > /etc/rc.conf has: > devfs_system_ruleset="localrules" Looks correct, but doesn't seem to be sufficient. But take into mind that /etc/devfs.rules is used for dynamically allocated devices, and /etc/devfs.conf for those present at boot time (usually cd, maybe also da and ada depending on your setup).
