<tr class='nohover-highlight'><td/><td colspan='3' class='logmsg'>
Requiring the user to input their password in order to unlock a device is not
always reasonable, so having an option to unlock the device using a key file
is a nice quality of life change.

* gnu/system/mapped-devices.scm (open-luks-device): Add #:key-file argument.
(luks-device-mapping-with-options): New procedure.
* doc/guix.texi (Mapped Devices): Describe the new procedure.
