make a /root/bin/myshutdown script and run that instead perhaps.

Off the top of my head (and requires debugging)
#!/usr/bin/env (ba)sh # (your choice of bash or sh)execute-your-cmd-hereshutdown -r now # swap -r for -h if you wish to halt instead of reboot



inversely you can 'man (or info) bash' and learn how to use case so you can pass switches to your script ... i.e.*
/root/bin/your-shutdown-script -r*


or
/root/bin/your-shutdown-script -h
If given enough inclination, I might be able to write something in python (albeit it crude and*rudimentary*but it should get the job done)

Make it an init script that is only called in runmodes 0 (for shutdown)
and 6 (for reboot)? I think the proper way to do this would be to set
Default-Start to "Default-Start: 0 6" in the header.
