[pkg-cryptsetup-devel] Bug#967853: cryptsetup: does not support bitlk type in crypttab

[Thomas Luzat]

Package: cryptsetup
Version: 2:2.3.3-1+b1
Severity: minor

systemd 246 (Debian version 246-2 here) added support for Windows BitLocker
volumes. It requires a bitlk type specified in /etc/crypttab for systemd-
cryptsetup, like so:

foo PARTUUID=12345678-abcd-abcd-abcd-1234567890ab /etc/cryptsetup/foo.key
bitlk,discard

Debian's cryptdisks_start does not require the bitlk option in that case, but
also does not support the option. This results in a warning when Debian's
scripts are used:

# cryptdisks_start foo
Starting crypto disk...cryptsetup: WARNING: foo: ignoring unknown option
'bitlk'
foo (starting)...foo (started)...done.

It would be nice if bitlk was either required (for consistency with systemd) or
at least allowed to avoid that warning.
