When looking into the documentation (28.2.1) and also while testing, it
seems that it is not possible to give a tenant access to a fileset like
it was a regular lustre fs.

I would like to map IDs to a separate range including root (0). This
works when admin=0 for the nodemap, but then root will not be able to
modify other user's files. In admin=1 mode, root is not mapped and will
become id 0 on the underlying fs.

Have I missed a way to accomplish this? If not it would be on my
wishlist. Mapping ranges is also on that list.

I could also see a lot of quota control scenarios for this kind of
setup. I.e. allow to control quotas for mapped UIDs and GIDs, but not
