Some stuff cannot be done on a single line, so I have abused the _aliasX mechanism for that. With the bridge interface: ifconfig_bridge0="ether 00:00:24:c0:0e:40 addm sis0 stp sis0 addm sis1 stp sis1 up" ifconfig_bridge0_alias0="inet 146.64.84.1/24" Also with the atheros driver I had problems in the past with some parameters that did not like to be on a single commandline. FWIW I do not find the "ifconfig iface -alias" to be a problem... probably because I'm used to it. :-) What I do find silly is that you cannot do "ifconfig iface tunnel inet6 <inet6_addr> <inet6_addr>" anymore. It used to work and is still documented in ifconfig(8) to work. You have to swap inet6 and tunnel for it to work. John -- John Hay -- John.Hay@meraka.csir.co.za / jhay@FreeBSD.org
