The only thing that is "wrong" in your plan is "So I'd check what
systemd unit (units) does (do) the job of mountall.sh".
The "right" thing would have been "So I'd check the documentation to
see what unit...": one place with things explainev vs. what looks like
reverse engineering.
That's not for me, some more tinkering or some less tinkering does not
change the things this much.
But I fear a situation like this:
Random J. Hacker: "We could use a Debian stable server for this, but I
have to go and see how to port our boot script ..."
Project M. Anager: "Go and see?"
Random J. Hacker: "Yes, they changed the boot process and the documentation
does not cover all"
Project M. Anager: "No, we will stick to $whatsoever, we have no budget for
with old sysV init, we have non budget for..."
[Please note: mrs. Project M. Anager at least knows what she is
talking about]
On an issue like this documentation is critical. Let's hope that RH
interest in systemd will give us this kind of documentation...
