Description of problem:
Installing Canna package fails to create a group and a user in %pre script.

Version-Release number of selected component (if applicable):
selinux-policy-3.10.0-54.fc17.noarch
selinux-policy-targeted-3.10.0-54.fc17.noarch

How reproducible:
always

Steps to Reproduce:

2.
3.
  
Actual results:
warnings appears like:
warning: user canna does not exist - using root

Expected results:
no warnings

Additional info:
scriptlet itself doesn't fail because it has "exit 0" at the end according to https://fedoraproject.org/wiki/Packaging/UsersAndGroups. I built the testing package got rid of it; http://koji.fedoraproject.org/koji/taskinfo?taskID=3523256

Installing it with rpm gives me an error like:
groupadd: cannot open /etc/group
useradd: group 'canna' does not exist
error: %pre(Canna-3.7p3-33.fc17.x86_64 scriptlet failed, exit status 6
error: Canna-3.7p3-33.fc17.x86_64: install failed

It works fine on Permissive mode.
