Description of problem:
On a fresh install, trying to use chsh to switch to the any other shell -- e.g. using 'chsh -s /bin/zsh' fails, with a message that the selected shell is not in /etc/shells.

As it turns out, on a fresh installation /bin/bash is *not* in /etc/shells.
The problem seems to go away as soon as bash is reinstalled/upgraded; I seem to remember seeing this on my F16 box too but now chsh works fine there.

Version-Release number of selected component (if applicable):
util-linux-2.20.1-5.fc17.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install a new system (from live CD)
2. cat /etc/shells
3. chsh -s /bin/dash
4. yum reinstall bash
5. cat /etc/shells
6. chsh -s /bin/dash
  
Actual results:
step 2 =>
/sbin/nologin
/bin/dash
/bin/zsh     # I have zsh installed

step 3 =>
Can't change shell:
chsh: chsh: your shell is not in /etc/shells, shell change denied: Permission denied

for steps 5 & 6, see expected results

Expected results:
step 5 => these two lines are added at the end of /etc/shells

/bin/sh
/bin/bash

step 6 => works

Additional info:
On this particular system, I have upgraded to Rawhide after installing from the Fedora 16 live CD, so really, bash has been upgraded and the %post steps should have been run. No idea why either on F-16 + updates, or F-16 upgraded to Rawhide (in this case, Rawhide's usr-move repo) bash still does not register itself in /etc/shells.
