Check if the filesystem is supported by the kernel before trying to
mount it. Systemd-mount will mount the directories asynchronously
resulting in stale directories if the devices filesystem is not
supported.

We once went through the init scripts and carefully minimised all the
fork() calls in them, since all that process execution overhead does
mount up and delay boot times.
I really don't know what to do, whether I should continue to care or
not. It is easy to say systems have plenty of memory/cpu and therefore,
"who cares?". Equally, systems working efficiently is nice to have...
Not sure if correctly interpreted, but it seems that there are some
"frustration" vibes in your reply :)
I was not aware of the discussion but understand what you are trying to
achieve. We can replace the 'cat' with a 'read', which should avoid the
fork() since it's a shell-builtin (correct me if I'm wrong).
Best regards
Lukas
Cheers,
Richard
