After a bit of playing around, I realised that ypserv on the slave needs to have
a populated /var/yp/<domain-name> directory before it will accept maps being
pushed from the master.

This makes sense - it firstly tells the daemon what domain(s) it is handling,
which maps are handled, and whether the maps are up to date with those on the
master.

So, I created a tarball of the master /var/yp/OSA, copied to my NFS shared home
directory, and untarred into the clients /var/yp. Then I kill -9'd ypserv ("and
nuke the site from orbit, it's the only way to be sure"), and restarted it.

And it worked good.

This is one of those things that seems so obvious is hindsight, but which don't
seem to be clearly documented anywhere for those of us who have colanders for
brains...

Thanks for your help...
