IP aliases not sticking around

["Chris Cameron" <chris@upnix.com>]

I have an alias attached to my xl0.

My hostname.xl0:
inet 209.82.111.158 255.255.255.240 NONE media autoselect
inet alias 66.46.111.238 netmask 255.255.255.240
#dhcp media autoselect

I -believe- this was what was suggested in the FAQ, but after a reboot, the
alias wasn't sticking around.

Any ideas?

Thanks,
Chris
