I have luks set up on my server and it is kind of annoying to type the password at reboots (mostly power outages). Strictly speaking I do not need the luks, but I feel its good to have anyway. I was thinking of getting a yubikey and just leaving it on or at least telling a trusted family member where to get it and to plug it in when turning it on.
Has anyone over come a similar set up or issue?
For some clarity I am not a pro and the homelabing is mostly just a learning experience for me.
Sounds like all you need is an Ext4 USB drive with a LUKS key on it. Then add a kernel parameter like rd.luks.key=UUID=/.keys/TheKey:LABEL=KEYS-timeout=10s in GRUB and it’ll autoboot.
Pull the key and power down and you’re back to normal. I use it in a low threat model environment so I can hit reboot and go get a coffee and come back to a DE.
