Good day/night.
I have been having some troubles with devfs (the config files that is).
Here is what I want todo:
I want to be able to allow users in group 'cdrom' to acces (rw) to /dev/acd0
First of all i created the group ;). So far so good.
Then i uncommented this line:
link acd0 cdrom
in /etc/devfs.conf (My only change in that file, so far).
So far so good.
Now heres where the trouble begins: I can by using the command line utility
(devfs) allow users in group cdrom to rw /dev/acd0{cdrom}
By issuing the following commands:
# devfs ruleset 10
# devfs rule add path acd0 group cdrom
# devfs rule add path acd0 mode 0660
# devfs rule applyset
Here I have:
[thib@caulfield thib]$ ls -al /dev/ | grep acd0
crw-rw---- 1 root cdrom 4, 21 Nov 9 23:11 acd0
lrwxr-xr-x 1 root wheel 4 Nov 9 23:11 cdrom -> acd0
So far so good.
But when I add these lines:
own acd0 root:cdrom
perm acd0 0660
to /etc/devfs.conf
I get this:
/etc/rc: WARNING: devfs_set_ruleset: you must specify a ruleset number
/etc/rc: WARNING: devfs_apply_ruleset: you must specify a ruleset
in my dmesg.
Okey. So I took a look in /etc/defaults/devfs.rules and did the following:
(PS: I removed the own/perm lines in /etc/devfs.conf
# touch /etc/devfs.rules
And added these lines to the file:
[devfsrules_cdrom=10]
add path acd0 group cdrom
add path acd0 mode 06660
When I reboot I get the same error messages:
/etc/rc: WARNING: devfs_set_ruleset: you must specify a ruleset number
/etc/rc: WARNING: devfs_apply_ruleset: you must specify a ruleset
Here's the kicker, even though I get these error messages it "DOES WHAT I
WANT"...
My questions is, what is the proper way of specifying a ruleset in either
/etc/devfs.conf or /etc/devfs.rules and wich of the files should I use ?
I'm sorry if I missed something obvious in the manpages (or did not google
enough).
Please CC me for I'm not on the list.
