Hi James,

/sys is an interface to drivers, like the qeth driver.  /sys comes
only with 2.6 kernels, like SLES9.

As an example, you can echo 1 or 0 to a file in /sys (don't have
access to a z/VM Linux machine right now - something like /sys/
drivers/qeth/ccwgroup/... ) to turn online or offline a qeth interface.

As far as I know, there is no need to backup /sys and /proc.

Hello,   First time posting on here, but enjoy going through the

quick backround.
Running sles 9 under VM 5.2

I was using rsync to do a few directory level backups, and get a
handfull
of permission denied on /sys/devices/qeth  files.
It seems these files are --w-------  only.     Can someone give me a
reason why, and if it would be ok to change them to rw?
Thanks.
