What is hwclock? ;-)
That utility is not compiled / used on s390 distributions. We could add
genrtc, readd hwclock to the util-linux compile for s390 and just call
it in the init scripts. Some of the current scripts have something like
  if [ `uname -s` == "Linux" -a `uname -m` != "s390" ]
  then ...
around the calls to hwclock.
And it would be easy to do, just remove the !S390 from the GEN_RTC
option in my cleanup patch.
