Alternatively, create/edit /etc/pw.conf including minuid 2000 maxuid 4999 reuseuids yes This will cause automatic uses of pw(8) (such as port installations) to use uids between 2000 and 4999, and to ``fill in the gaps''. When adding a user by hand, use pw -C /dev/null to tell pw to ignore pw.conf(5) and get the default behaviour (which is to use the uid one higher than the highest ever used). adduser(8) should just DTRT, but you can make sure by adding to the flags -u uid_start which will use the next available uid after uid_start (which it identifies by testing each uid in turn for existence, not by just using pw usernext).
