The problem is that there's two competing mechanisms for network management. NetworkManager is primarily used for mobile installations (e.g. laptops and such), whereas the the normal stuff (/etc/rc.d/rcX.d/S10network) is used for more fixed locations. The startup scripts could be modified to see which was the case, but that'd have to be extended to all services that were dependent on the network. On my F7 machine, that's at least 31 services (NFS, RPC, ntpd, iptables, avahi, mail, NIS, lots of stuff). Alternately, the %post part of the NetworkManager RPM could add entries to /etc/NetworkManager/dispatcher.d and "chkconfig off" the services. A utility could also be written that did it (e.g. "nmconfig --enable" or "nmconfig --disable", possibly with a GUI front end as well). Perhaps an "enhancement request" filed against NetworkManager in bugzilla would meet with a favorable response. ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - CDN Systems, Internap, Inc. http://www.internap.com - - - - Sarchasm: The gulf between the author of sarcastic wit and the - - reader...who doesn't get it. - ---------------------------------------------------------------------- -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
