Yes it is feasible; but, Sun refuses to support this configuration which
many of us believe in dearly.  You don't say what version of SunOS you are
running, but I believe that the magic incantation is the same for both 3.X
and 4.X.  In your configuration file you want to "specify swap on ????",
where you fill in a disk partition name like sd0a for the question marks.
This incantaion goes on config line and is documented in the Sun manuals.
As I remember, there may be some problems in certain versions of SunOS if
you don't explicitly specify all of the fields on the config line when
trying to take advantage of the swapping only configuration.

Trying the kernel config line of:

	config vmunix root on type nfs swap on sd0c

works perfect for any diskless 4.0.3 client with a local scsi. or:

	config vmunix root on nd swap on sd0c

works fine for any diskless 3.X client with a local scsi.

just be sure that sd0 has a valid drive lable and you are in business.
you should note that the internal scsi drive on a sparc is acutally slower
then an nfs file system providing network performance is acceptable....
