>Description:
It seems silly that you have to renumber the ifconfig aliases in
/etc/rc.conf when you remove one -- because they are number based
and count up sequentially.
>How-To-Repeat:
The manpage for rc.conf describes this functionality and the
script chunk replaced by this patch will clearly function this
way.
>Fix:
