This didn't make it out the first time as I was silly enough to
put "Re: SUMMARY" in the subject line...

Following my summary, I've received some more responses, which take us
a bit closer to consensus. We haven't installed -08 as yet, but will
in the near future (tomorrow!). Here is the previous summary and
what I've learnt since:

Findings since this summary:

100075-08 is necessary for 4.1.2 or a mixture of 4.1.2 and 4.1.1
clients. Some sites have had success with rev 07 with 4.1.1 only
but I wouldn't recommend it. Rev 08 seems to be the way to go -
and use it everywhere.

A known problem with 100075-08 (and possibly all versions of) rpc.lockd
is locks on the server are not released when a client crashes if you use
TMPFS for /tmp. Sun apparently have a fix but only on special request.
