Hello Karel,
The bcachefs has the helper called mount.bcachefs.
Currently, there are users using fstab with nofail/user fail to mount,
we would like to know whether other filesystems using similar helper
properly handle this.
This is like commit 06e05eb0f78566b68c44328c37d7c28d8655e9df
(“libmount: don't pass option "defaults" to helper")
Or would you like something like this? This might be incomplete though (e.g. owner, noowner etc.)
