Description of problem:
After latest upgrade to latest FC2 .rpms ("apt-get upgrade") normal
users can not issue a "poweroff" command.

Version-Release number of selected component (if applicable):
libselinux-1.13.2-1
libselinux-devel-1.13.2-1
selinux-doc-1.10-1

How reproducible:
Always.

Steps to Reproduce:
1. Install FC2;
2. Upgrade the system with "apt-get upgrade";
3. Log in as normal user and issue "poweroff";

Actual results:

[ivo@sarmax ivo]$ poweroff
Could not set exec context to ivo:sysadm_r:sysadm_t.
[ivo@sarmax ivo]$

Expected results:
System going down.



Additional info:

I find it odd that if the user should press the "ctrl+alt+del" then it
will reboot the box, but issuing "poweroff" is not accepted.

Why the SELinux is active despite /etc/sysconfig/selinux has
"SELINUX=disabled"?
