Post subject:  shutdown from command line always shuts down immediately

New installation of LinHES R7.4

Code:
shutdown -h 02:10

should shut the machine down at 02:10am according to the documentation.
It always shuts down immediately.
/sbin/shutdown script isn't written to deal with this situation [edit: if runit is in use rather than init], it only understands -t delay option.
I realise LinHES is an appliance but this came as a surprise.
Bug or undocumented featurette?

Notes:
1. Calling shutdown.init directly (eg: shutdown.init -h 02:10) results in:
...
shutdown: /dev/initctl: No such file or directory
init: /dev/initctl: No such file or directory
...

2. Trying to workaround using "at" command failed, there's no "at" in the repos.

It's neither a bug or undocumented feature, it's just how it is.

The commands shutdown/halt/reboot are shell scripts provided for convenience.
-t was added because someone needed it, Likewise -h support can be added or halt.c patched to avoid the runlevel check whichever is easier.

Thanks for that info. jams; I feel happier knowing I can wade in and adapt it to my own needs.
