Documentation Error?

[Jason D. Montgomery]

Odd. I'm no guru, so it may just be my lack of understanding...

I had this in my rc.config file to setup an alias on a NIC:

ifconfig_xl0="inet 192.168.20.2 netmask 255.255.255.0"
ifconfig_xl0_alias0="inet 192.168.20.3 netmask 255.255.255.255"

And the alias'd address would NOT load at boot time. Couldn't get it to
work.

But when I changed it to this, it worked just fine:

ifconfig_xl0="inet 192.168.20.2 netmask 255.255.255.0"
ifconfig_xl0_alias0="alias 192.168.20.3 netmask 255.255.255.255"

The ifconfig command wouldn't work either until I replaced alias with
inet on the command line. 

Am I just missing something else?

FYI:

# uname -a

later,

man rc.conf and search for "network_interfaces".  The reason it still 
works is that if you do a simple test with your ifconfig both:

ifconfig wi0 192.168.0.6
ifconfig wi0 inet 192.168.0.6

....work as you would expect.
