SubjectRe: file locking over NFS in 2.2.7

What about the case where a partition on a Linux server is mounted
by a Solaris client? Solaris does not have a 'nolock' option for
NFS mounts, and some software (eg Sendmail 8.9.3) insist on doing
some sort of locking (Sendmail will always use either fcntl or lockf).
It looks to me that knfsd is not quite stable yet, so I'm reluctant
to move my production machines to it.
