useradd --system warns when the uid it is given is above SYS_UID_MAX,
999 on Ubuntu; --key raises that limit for this one call, so the uid
stays 65532.
minsysusers, which runit's install runs to create its _runit-log user,
prints a Perl warning because runit's sysusers line leaves out the
shell. It reads /etc/sysusers.d/runit.conf in place of runit's file, so
the image writes a copy of that line there, naming the shell minsysusers
gives anyway; the user it creates is unchanged.
The runsvinit warning stays, since it needs a change to runsvinit: its
reaper and its own wait on runsvdir race for the same exited process.
