Thanks for all the suggestions and links.

I will try putting a new / temporary key into the initramfs just for while I am out of town - the chance of power outage is higher than the chance of burglary.

I'll remove the temp key and rebuild the initramfs after I get back home. Normally, I'm in front of the computer when it reboots, so entering the password manually (as I've been doing for a few years) is fine.

Is there a good way to have a #Linux server reboot unattended when the root partition is dm_crypt encrypted? I'm not super worried about bad guys being physically present. More just worried that a power outage might initiate a reboot while I am not present.

Is including the key file in the initramfs (correct terminology?) that horrible a thing if physical access to the machine is not a concern?

Thoughts or advice?
