No I've done it on servers that weren't single-user (mail and web
servers in particular).  Not sure what you're getting at there, or why
that's relevant.  All Linux machines are set up and run as multi-user
boxes anyway.  Even my laptop that only I use.

Well since I have no idea what you were trying to do I can't comment.

That sounds frustrating, but of course I've heard similar stories from
folks moving to Python 3. :)

I've yet to encounter any of those kind of problems your admins
apparently had.  Also systemd in no way prevents you from using init
scripts or even inetd services if you choose, so there's always a
fallback position.

I'll have to specifically ask my friend who works for Bluehost about any
systemd troubles next time I speak with her.
