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 :)

sysadm list - just me being stupid!
