Comment 20 for bug 569757

On my mail server postfix and dovecot depend on nis. Currently this particular dependency is handled properly, because all three daemons are started by means of /etc/rc?.d in the correct order. Please correct me if I am wrong, but I worry that the solution suggested by Clint Byrum in #18 might cause nis to race with postfix or, if postfix is converted to "native upstart", with dovecot. Anyway, the start condition for nis-wait would have to be extended to list all possible nis dependencies, and there could be plenty of them, seeing that nis provides very basic system information such as users, groups, etc. So we would have "start on starting gdm or starting autofs or starting postfix or starting dovecot or starting kdeinit4 or starting ...", and so on.
