The chzdev command also simplifies things. It's part of s390utils-base.

Hi, Phillip,
Thanks for using ClefOS
1. This is just my OCD talking, but I would 'protect' that
echo, as a matter of defensive coding
echo "0.0.204,0.0.205,0.0.206" > \
/sys/bus/ccwgroup/drivers/qeth/group
I know, I know -- OCD
2. What is shown with:
# ls -l /sys/bus/ccwgroup/drivers/qeth/
I get this locally:
[root@lclef01 ~]# ls -l /sys/bus/ccwgroup/drivers/qeth/
total 0
lrwxrwxrwx. 1 root root 0 Jul 9 16:23 0.0.0340 -> \
../../../../devices/qeth/0.0.0340
--w-------. 1 root root 4096 Jul 13 16:28 bind
--w-------. 1 root root 4096 Jul 9 16:23 group
lrwxrwxrwx. 1 root root 0 Jul 13 16:28 module -> \
../../../../module/qeth
--w-------. 1 root root 4096 Jul 9 16:23 uevent
--w-------. 1 root root 4096 Jul 13 16:28 unbind
This is pointing up into:
/sys/
and particularly I see there:
[root@lclef01 ~]# ls /sys/devices/qeth/
0.0.0340 module power uevent
[ I have indicated the line wrap with backslashes, although of
course not really there ]
The parallels on my settings for completeness:
