Hello, [email protected],
I am exploring the feasibility of adding colorization of subvolumes to
the output of the coreutils `ls` program. Specifically, for the
BTRFS, ZFS, and Bcachefs filesystems.
In order for `ls` colorization of subvolumes to be feasible, detection
of subvolumes, by non-root users, needs to be implemented in an
efficient and reliable manner.
In searching the linux-bcachefs mailing list, I found a post by Kent Overstreet:

Still todo:

find -xdev does what you want and skips snapshots

What is the status of the above todo item regarding a distinct st_dev
value for each subvolume?
A second question: On Btrfs, each subvolume has an inode value of 256.

Is there any easy method for users (especially non-root users) to
identify Bcachefs subvolumes?
Thank you,
Parke
