Everything under /sys is managed by the kernel, not by UDEV. So you
are correct, that sym-link was not created by UDEV.
There are changes between the kernel shipped with SLES 10 and that
shipped with SLE 11. If you have home-grown scripts (as many of us
do), you'll have to adjust them. Looks like the link you're after
changed from
/sys/devices/dcssblk/PERFOUT/block:dcssblk0
to
/sys/devices/dcssblk/PERFOUT/block/dcssblk0
(if I am reading the traffic correctly).
Off hand, I forget the expected contents, and I don't have a DCSS
handy or I could confirm this for you.
