I am aware of that. I was just dreaming of a perfect solution, very
well knowing that I won't get it RSN.

Yes, but GNU/Linux is not a "grüne wiese" approach, it is migrating
millions of existing systems.
Even a classic Unix leaves many things to be hated, but it's just what
we are used to, and which is not easily changed.

Locking a shell for a two-digit number of seconds in a ordinare usage
situation is something I would not want to adapt to even if the
underlying system was perfect.

I fail to see why it is "progress" to save five seconds of shutdown
time for the machine while the same change wastes half a minute or
more for the human.

Marc, well aware that the last sentence will be misinterpreted as
systemd hatred again, which it is not
