Hello,

I am migrating my server from Slackware Linux to FreeBSD (decided to try).
Unfortunately, I chose to install 3.1-RELEASE (now I see that 2.2.8 might
be better). I have couple of questions related to NFS server.

1) I can't export directories which are not local mount point. E.g., I
have disk mounted on /vol1 and want to export only /vol1/ftp . Is this
possible (if I try to export /vol1/ftp/.1, mountd complains about wrong
mount point)? Even worse, I need to export /var/spool for pcnsfd printing,
but don't want to export entire /var. In my case, /var is on separate
partition.

2) NFS mount does not seem to go through local filesystems. E.g., I have 
another disk mounted on /vol1/ftp/.1 and want export of /vol1/ftp to
transparently "bleed" through to /vol1/ftp/.1 ?

2) On Linux, I was able to re-export NFS-mounted directories. E.g., in the
above example I mount via NFS /vol1/ftp/pub/zeus from zeus:/sai2 and want
it to be seen via NFS export (/vol1) as well. Is this possible?

I thought it might be possible to get it if I bypass kernel NFSD and
install different NFS server, but mountd coredumps if I disable NFS in
kernel on 3.1-RELEASE...
