No; I do that, as well (for a couple of "client" machines), but they're
tracking stable/9, rather than head.  (I'd switch them to stable/10, but
they run authoritative name servers, and I haven't figured out a
reasonable way to do that migration because of the way the installation
of the dns/bind99 port depends on the version of the OS at install (vs.
run) time.)

I would expect it to work -- at least, if the machines are all
reasonably closely synchronized with respect to time-of-day.
Oh -- and if the machines have compatible /etc/{make,src}.conf files.

IIRC, I also ended up needing to create a symlink or two.

Well, that should take care of the time-of-day (potential) issue.

Sorry; it's been a long time since I encountered anything similar to
that, and I no longer recall what might have contributed to it.  But I
do definitely do NFS installs; ref.:
