Well, here's what happens with that patch:

{subway:/usr/home/ken:2:0} sysctl -a |grep kernel
kern.bootfile: //kernel.test

netstat, etc., works okay, probably because the leading slash is discarded.

And here's what happens without the patch, when kernel.test2 is booted:

{subway:/usr/home/ken:1:0} sysctl -a |grep kernel
kern.bootfile: /kernel

Could it have something to do with the boot loader?  /boot/loader is from
my buildworld on Saturday, but one thing I've noticed is that the text that
comes up before the boot loader prompt ("FreeBSD/alpha SRM disk boot,
Revision 0.1") is dated September, 1998.  So it sort of seems like
/boot/loader may not be what is used here..
