I'd say yes and I agree on both points. This is also a perfect opportunity to mention systemd-sysusers(8) which, along with sysusers.d(5) entries, can greatly simplify the creation of system users. For an example, check out the openldap package: https://projects.archlinux.org/svntogit/packages.git/tree/trunk/slapd.sysusers?h=packages/openldap https://projects.archlinux.org/svntogit/packages.git/tree/trunk/openldap.install?h=packages/openldap
