> Please note that there are several independent cryptsetup wrappers with their own crypttab format.

If cryptsetup themselves don't provides `crypttab(5)`, we needs to figure out what options they provide.

The link you provided is specific for systemd, I don't use crypttab at all even if I use FDE (except /boot)
