Future Linux support

[lexx9999]

Linux support would be nice in general.

[lexx9999]

• use something similar to the agent which runs as sudo, then return the result
• linux may need to support different tools (dislocker, cryptsetup) though dislocker seems standard
• worst case the agent is sort of a shell script
• linux MachineId cat /etc/machine-id
• use direct stdin/out capture (no named pipes neccessary) with sudoers only
• run on terminal (needs detection or config), or pkexec (not mac), requires filebased ipc (requires proper file security/encryption)
