Just curious:

- Do such clashes occur really often enough to require special policy?

- Is leading underscore in login name guaranteed to not clash with existing
  account names on end systems? Perhaps one of the characters discouraged
  by passwd.conf(5) would be a better candidate?

- Will this policy extend to system users and groups added via Pkgsrc?
