Speaking of dhclient and aliases.  Has anyone sucessfully used the
alias { ... } syntax of dhclient.conf after switching dhclients?  I
used to use the following in my dhclient.conf, but had to comment it
out when the OpenBSD dhclient was imported.

|alias {
|  interface "sis1";
|  fixed-address;
|  option subnet-mask;

I hope to check out this patch shortly.  Thanks.
