Thanks, you're right - this has nothing to do with mountdtab or
mounttab. The commit that caused these messages to appear is
phk's centralisation of the kernel netexport structure:
REV:1.149 ffs_vfsops.c 2001/04/25 07:07:50 phk
Move the netexport structure from the fs-specific mountstructure
to struct mount.
...
Doing a MNT_DELEXPORT mount used to be a no-op if there were no
exports, but now it returns EINVAL. Maybe that should be changed
to ENOENT or something, so that mountd can detect it as a 'normal'
error? (untested patch below).
