Is it right that I can use the -alldirs option just if the
dir to be mounted is a filesystem/partition?

And what is so the problem if I attempt to mount a root
for a diskless client just from a non-FS-subdirectory of a server,
i.e. I can not use the -alldirs option.

By the way one should have a look at the "man diskless"-page and
find out if this becomes really clear. I believe it does not :-(
