I think you and I have rather different defintions of "already doing it 
well" -- "I'm used to it" is not the same thing.

In this particular case, systemd has precisely two required components, 
systemd-pid1 and systemd-journald.  From systemd's persepective, 
absolutely everything else is optional and can be replaced.

Now specific linux distributions may or may not make it easy to replace 
its use of specific systemd components, but that's always been the case 
(distribution "differentiation" and all that) and isn't really systemd's

Post-systemd, that task is as difficult as it was pre-systemd.  (Yes, 
I've done this before in the process of building embedded distros meant 
for Wifi access points -- and believe me if systemd was an option ten 
years ago I'd have chosen it in a heartbeat.  It would have saved 
literally months of effort!)

That's the distro's fault, not systemd's.  Then again, udev has been a 
core package for mainstream distros for far longer than systemd has been 
around, so I'm not sure why you'd even be manually installing it.

You're going to have to be more descriptive than "does stuff", beause 
from systemd's own documentation, it won't touch intramfs unless 
explicitly told to do so.


So, blame your distribution for choosing to use systemd's features to 
simplify their bootup and restart processes..

Again, only if requested, but even then... so what?  A whole lot of 
other stuff is utilized upon a (clean) system shutdown.
