> Yes, I can remount the sub-volume with the mount command anywhere and with
an arbitrary name. In fact the thing that seems strange to me is that when I
create a snapshot, immediately it is mounted: it is not a real problem, it is
only a strange behaviour. The "standard" behaviour is to create the
file-system and then mount it: two separate actions.
GB is correct: Tru64''s ADVfs snapshots, which were (are?) essentially
the same as btrfs snapshots, were (are?) not mounted on creation

http://www.tru64unix.compaq.com/docs/base_doc/DOCUMENTATION/V51B_HTML/MAN/MAN4/0124____.HTM

indicates that these things were (are?) called "clones"

and
http://www.tru64unix.compaq.com/docs/base_doc/DOCUMENTATION/V51B_HTML/MAN/MAN8/0048____.HTM

 Here''s the example code for creating and mounting a clone with tru64
ADVfs, from clonefset(8):

  The following example creates a read-only copy of the credit_fs fileset
  that resides in the accounts_dmn domain.  The clone fileset name in this
  example is credit_clone1.  This example also performs an online backup and
  removes the clone fileset after the backup is complete:

       # mkdir /mnt/credit_clone1
       # clonefset accounts_dmn credit_fs credit_clone1
       # mount -t advfs account_dmn#credit_clone1 /mnt/credit_clone1
       # vdump /mnt/credit_clone1
       # umount /mnt/credit_clone1
       # rmfset account_dmn credit_clone1
