Addition is already implemented (I mean, that's the whole point)... removal
*probably* won't be, as it could very easily lead to UID collisions (e.g.
you remove an account which had UID 994, and then a week later you add a
different account with UID 994).

Note that sysusers is meant for *system* accounts (daemons, services, etc.)
– not for human accounts.

It's in the same place as other default services. Try `systemctl cat` or
`systemctl status` and it'll show the path. (Assuming your distro hasn't
removed the service entirely, that is...)

For human accounts? In general, the service isn't meant for that. Deploying
a sysusers config with static UIDs to all your machines would work, but I'd
say it's overkill – after all, you could just use the same configuration
deploy mechanism to add accounts directly. Most sites use LDAP or NIS for
that purpose.
