Description of problem:
With selinux in enforcing mode, system processes are
hidden from normal users. In particular "pidof <command>"
doesn't work for system processes.

A consequence of this is that a normal user
"/sbin/service <service> status" says the service
is stopped even if it is actually running.

How reproducible:
Every time

Steps to Reproduce:
0. Install test2 and login.
1. % service sshd status
2. % service canna status
3. su -
4. # service sshd status
5. # service canna status

Actual results:
1. sshd dead but pid file exists
2. cannaserver is stopped
4. sshd (pid 2536 2532 2068) is running...
5. cannaserver (pid 4541) is running...

Expected results:
Consist results.  If service can't tell the pids
of system processes to normal users, it should
say so (eg "Permission denied" or similar), rather
than giving inaccurate responses.

Additional comments:
The xinput script currently depends on service status output.
Canna comes with cannaping whose exit status corresponds to
whether cannaserver is running or not.  But implementing
"<service>ping" for every daemon in the distro seems like
a lot of work...
