Note that "systemd-analyze verify" already checks unit files for
correctness. It

Often seen mistakes:

- An early-boot service (DefaultDependencies=no) that orders itself
  after later boot services

- Services referencing syslog.target

- Late-boot services referencing local-fs.target

- Services that needlessly specify StandardError=journal
  (or even StandardError=syslog) (the former is now the default)

We probably should add chekcs for these to "systemd-analyze verify"
even...
