I've been reading the FHS specification on http://www.pathname.com/fhs/pub/fhs-2.3.html to figure out where a (private) SSH keyfile should be stored that will be used for a VPS administration panel I am currently working on. This keyfile should only be available to the master server (the one it is placed on), and will be used to tunnel libvirt communication over SSH.
From my understanding, this means the keyfile should be stored in a subdirectory in /etc, as it is static and host-specific. Is this correct?
