Is there a generic name for both volume and subvolume root?
Nope, subvolume (including snapshot) is not distinguished by its
filename/path/directory name.
And you can only do snapshot on subvolume (snapshot is one kind of
subvolume) boundary.
So, I can name a btrfs root volume also btrfs subvolume?
Yes, root volume is also a subvolume, so just call "btrfs root volume"
a "subvolume".
I am talking about documentation, not coding!
I just want yo use the correct terms.
If you're referring to the term, I think subvolume is good enough.
Which represents your original term, "directories one can snapshot".
For the whole btrfs "volume", I would just call it "filesystem" to avoid
the name "volume" or "subvolume" at all.
Thanks,
