At the moment I don't, but I have in the past and have no real doubt I
will in the future.

Back when I worked with a smallish (10-20) farm of mostly-diskless
machines, it was not uncommon to have most machines set up with an
fstab that looked something like (to use NetBSD syntax)

server:/nfs/root/myname / nfs rw
server:/nfs/usr/myarch /usr nfs rw
server:/nfs/home /home nfs rw
kernfs /kern kernfs rw
procfs /proc procfs rw

and then one or two of them with real disk adding a line or two like

/dev/sd0a /project ffs rw

or

/dev/wd0a /home/someone/something ffs rw

Such machines could, of course, be set up as fully diskful.  But in an
environment like that the benefits of keeping the machines' setups
_almost_ identical can easily outweigh the benefits of going diskful.

Sysinst won't do lots of things many people want.
