Trying to be compatible with all the various unices is not very practical. > Inefficiencies?

Something like the difference between booting in 2 minutes versus 45 minutes. Also if you do snmp and have a lot of interfaces to get data for, netlink really helps a lot too. Also the ip command has much nicer syntax and supports stuff ifconfig does not (or at least didn't for a long time, like multiple IPs on an interface). -- Len Sorensen _______________________________________________ lpi-examdev mailing list [email protected] http://list.lpi.org/cgi-bin/mailman/listinfo/lpi-examdev
