Yep, thanks Chris. I went with regular reboot and have now successfully used

scontrol reboot ASAP 

Very handy!

FWIW reboot is provided by the init system implementation (for instance
on RHEL6 it's from upstart), and /sbin/reboot is only optional in the
FHS. Only /sbin/shutdown is required by the FHS.

http://www.pathname.com/fhs/2.2/fhs-3.14.html

On proprietary UNIX versions reboot (not guaranteed to be in /sbin, it
was /etc/reboot on Ultrix 4, /usr/sbin/reboot on Solaris) may not run
shutdown scripts either (eg Solaris), you'd want to use shutdown for that.

cheers,
Chris

We have:

RebootProgram = /sbin/reboot

Works for us.

John, thanks. Yes, I have implemented reboot guard, which was why I was
asking if the config just wanted the link to a bin or could take a command
to execute.

Aaron, kind of. I noticed the anomaly yesterday for the first time and my
manager pointed me to this

https://amitksaha.wordpress.com/2013/11/21/poweroff-halt-reboot-and-systemctl/

Like Busybox, systemctl has reboot compiled in..

cheers

Good grief. "reboot" is a legacy tool?!?! I've about had enough of systemd.

Jeez... Look HPC compute node - I'm in charge, gottit? Yeah, fight back all
you like with systemd, but I can pull the power plug.
Let's see you deal with that one.
