Ah ok, that's why I can't find them!

On reflection, I agree. Both system and procps would have similiar triggers
because,
as you say, they're the only things that can do something about it.

I'm happy to work with the systemd developers to have a consistent set
of triggers across both packages. I'd expect the main difference besides
what
command is run is procps will need some sort of "is systemd running?" check.

I am concerned conceptually about setting kernel parameters while the
system is out
of boot phase. For example setting variables net.ipv4.conf.all/default will
do diferent things
due to network interfaces that exist, or will exist soon.

I don't see a fix for that; after all the issue this report is trying to
fix is we want these changes to immediately happen.
