This, unfortunatelly, highlights perhaps our biggest problem with starting services. rc.d basically only *orders* the scripts - REQUIRE is just "this service needs to be started after that one" - AFTER is just a lax checkpoint in the booting sequence And if a script doesn't really start the service, for whatever reason, there's 0 feedback mandeted/provided by the framework. For short, while everything works OK, it's good enough. If not ... it's just misleading. -- IOnut - Un^d^dregistered ;) FreeBSD "user" "Intellectual Property" is nowhere near as valuable as "Intellect" FreeBSD committer -> itetcu@FreeBSD.org, PGP Key ID 057E9F8B493A297B _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscribe@freebsd.org" ______________________________________________________________________ This email has been scanned and certified safe by SpammerTrap(r).
