I'll second that motion by an order of magnitude!

It drives me absolutely batty that I've got to build a new kernel just
to add some swap space, and if indeed I can't build a new kernel because
I don't have enough swap space initially available, then I'm hosed.

I still haven't figured out how to swap to a file, or even a vnode -- I
thought I had made all the right kernel changes to allow swap to a
vnode, but it still won't allow me to attach it, and I just gave up.  I
certainly need some such feature before I can finally ditch SunOS in my
production environments.
