Probably, but then cockpit would "eat resources".

Of course, running (x)inetd also eats resources but the question then
becomes whether running systemd consumes more resources then (x)inetd
plus your choice of init.

While I can understand your line of thinking, I think it's a bit of a
slippery slope. If projects decide to throw in their lot with systemd
(as in not accepting patches to cater to non-systemd setups), I think
they deserve to be plonked by distributions that don't support systemd.

Hope this helps,
