Public bug reported:
I have an external HD attached to an x86 box running Edgy, with latest
updates. The external HD has an ext2 and an HFS+ partition on it, both
of which are mounted read/write on the Edgy box.
I can export the ext2 partition over NFS just fine, but try as I might,
I can't export the HFS+ partition using nfs-kernel-server... client
always reports "reason given by server: Permission denied". This
happens even if the client is the Edgy box itself.
I can export the HFS+ partition from the Edgy box just fine if I use
nfs-user-server instead, with the exact same configuration (/etc/exports
file etc.), but that has the 2Gb file size limit which makes it useless
to me. I can also export the same partition with nfs-kernel-server if I
connect the HD to my PPC Macintosh running Feisty, and export it from
that instead. So it seems to be specific to kernel-server on x86 and/or
Edgy.
If it's any help, an strace of mountd during the failed mount suggests
the trouble spot is here:

open("/proc/fs/nfsd/filehandle", O_RDWR) = 10
fstat64(10, {st_mode=S_IFREG|0600, st_size=0, ...}) = 0

permitted)
