this rang a bell, so now i finally had a minute to check back thru the
mail, i see ivan asked a similar qn. We should probably pursue this but it
means a change in linuxmeister/build/init_buildsystem  -- which is
actually part of SuSE's build stuff. There is no current facility for
passing in --noscripts specifically, nor extra args in general.
Mark do you know how to go about getting such a change into linuxmeister?
Or recommend me someone to talk to? Im assuming we cant just change it in
our own copy? (in addition of course to suggesting same to SuSE)

2 possible stopgaps:
* restore the fallback to killall in oss, but not mangrove
* have pmcd log creation of the pidfile. Only call killall if there is
  a log file and it does *not* show creation of the pid file.
