Are there any standard solutions to rebooting an encrypted system remotely without requiring a password on the next boot?
The system in question is an Ubuntu encrypted with LUKS root partition and an unencrypted boot partition.
The only way I can imagine is to add a randomly generated second key that is based on a file resting on the boot partition and removing it with a start script on system boot.
Would the above approach work? Or is there a default option that does not require a manual approach?
The only security implication I can think of is that in case the system does fail the boot before starting the first services.
