Description Sergio Arroutbi 2022-06-21 13:56:49 UTC

Function clevis_luks_check_valid_key_or_keyfile is
spending most of the boot time dedicated to unlock devices.
However, this function is always returning true for an
already encrypted device (normal call execution).
Parameterizing this function to avoid this check allows
decreasing boot time per luks device
