We have a script we've used for some time based on Jesse David
Hollington's article on the Coolsolutions site.
http://www.novell.com/coolsolutions/trench/3359.html I was able to
adapt to most of the changes from ZEN 7 but I'm having a problem with
rebooting via a command line. I used to use the "reboot" command. Now
it just fails with the following message.

WARNING: could not determine runlevel -doing soft reboot.
(it's better to use shutdown instead of reboot from the
command line)

Trying "shutdown -r now" results in the following..

shutdown: cannot execute /sbin/init

The last odd thing I've figured out about this issue is, if you type
"reboot" at the command prompt manually, it reboots just fine. Just
not through a bash script. Anyone have any thoughts?
