True, but in these cases I think we are more looking at server or
mountpoint specific options than
actual fs tuning.
For example nfsmount.conf can be used to say "only use NFSv4 when
accessing server abc" etc.
For the case of CIFS I could imagine that an administrator might want
to set "disable smb1 protocol globally"
