  On a fresh install, indeed, there won't be a "mysql" user (yet) when
preinst is run. The check could be changed to something like
`if id mysql >/dev/null 2>&1` to gobble up any output that's produced.
I don't know if `adduser` needs the `--home` argument specified, as the
argument right before is `--no-create-home`.

  I was in a fresh, minimal install of sid. Then I just ran an `apt
install mariadb-server`.
