>Description:
I have this in /etc/devfs.conf:
perm bpf0 640
perm bpf1 640
perm bpf2 640
perm bpf3 640
Running "/etc/rc.d/devfs start" will create the devices:
[~] edwin at k7>ls -al /dev/bpf*
crw-r----- 1 root wheel 23, 0 Mar 8 16:46 /dev/bpf0
crw-r----- 1 root wheel 23, 1 Feb 27 15:09 /dev/bpf1
crw-r----- 1 root wheel 23, 2 Feb 27 16:46 /dev/bpf3
crw-r----- 1 root wheel 23, 3 Feb 27 16:46 /dev/bpf3
Only to see the next morning:
[~] edwin at k7>ls -al /dev/bpf*
crw-r----- 1 root wheel 23, 0 Mar 8 16:46 /dev/bpf0
crw-r----- 1 root wheel 23, 1 Feb 27 15:09 /dev/bpf1
(bpf1 is constantly opened by trafshow)
"devfs rule showsets" and "devfs rule show" don't return any
information.
