Subject: [PATCH] feat: respect old machine ssh host keys (#107)

When lustrating another machine, you usually are already connected by SSH. Thus, you usually already trusted that machine's keys.

With this patch, those keys are kept, so after booting into nixos, you still connect to the same trusted IP+Keys combination.
