+The glibc scriptlets don't seem to really *need* dash-static anyway...
+
+[root at jimmy ~]# rpm -q --scripts glibc| grep dash
+preinstall scriptlet (using /usr/bin/dash.static):
+
+
+So it's only the preinst script. That should be trivial to rewrite in lua.
+
+
+
+OK, so that does avoid the loop, but....... should we still try to work
+out a nice way to get "setup" (and thus the default groups that packages
+may use) installed early or is it just a housekeeping job to make sure
+packages Require(pre) setup package if they want to use the users
+defined in it?
+
+Perhaps we could add some kind of rpmfilter thingy to automatically add
+this Require(pre)? Is that possible? If so then it might also be
+possible to write similar automatic Require(pre,post,etc) to packages
+using rpm-helper stuff too... that would be be quire nice and reduce the
+packaging burden :)
