setup-2.8.5-1 is not installed to fresh chroot

here are two problems:

1. setup %post -p /sbin/postshell fails, because switch to glibc change:
http://git.pld-linux.org/?p=packages/setup.git;a=commitdiff;h=a0098a54771a73283ff3da722d9d6518a5d909d4

and that does not seem to work if glibc is not installed

2. rpm db is inconsistent that "setup" package is omitted from rpmdb but packages require it:
# rpm -r /tmp/rd -Va
Unsatisfied dependencies for glibc-2.17-6.x86_64:
   Requires: /sbin/postshell
   Requires: /sbin/postshell

Unsatisfied dependencies for mksh-44-1.x86_64:
   Requires: setup >= 2.4.6-2

there's actually third problem too. target files which are marked %config noreplace [1] (passwd, group) are overwritten (but not shadow!):

# echo p > /tmp/rd/etc/passwd
# echo g > /tmp/rd/etc/group
# echo s > /tmp/rd/etc/shadow

install to chroot when it first fails, then:
# poldek -r /tmp/rd/ -u setup; rpm -r /tmp/rd -q setup
