First, note that this is something I just threw together this
afternoon... it hasn't been deeply designed.
If a particular run-once had additional dependencies, presumably they
could be specified for its instance. Whether that'd let it reboot
safely... maybe. You'd really like to single-thread something that
wants to reboot the system, so that nothing else is in the middle of
doing its work.

I think you missed the "-c". That means "Hey, shell, here is a command
line. Process it.". What it means is that the command that you specify
must be acceptable to the Bourne shell. That command might well be the
name of an ELF executable, or a perl script, or... whatever.
You could set $RUN to any of
/opt/myapp/myprog
/bin/rm -rf /
echo hello
echo hello > /etc/passwd
echo $PATH
and they would all do sensible and obvious things.
