>Description:
              the new dhclient doesn't allow do have aliases on dhcp configured interface.

if I try to add alias via 'ifconfig rl0 alias ...' dhclient exists, leaving only aliased ip on the interface. 
adding alias statement to /etc/dhclient.conf 
will result in the same way. 
>How-To-Repeat:
              configure some interface via dhclient,
then try to add alias via ifconfig, or try to add 
alias lines to /etc/dhclient.conf
>Fix:
              may be it should by handled other way, but this works.
