install fai-server on the current machine
Initial setup of a fai server. works on localhost. Set's the current ip
work. Separate from running this, faiserver needs to be setup in dns to
point to whatever host this is run on.

+Default BASE_CODENAME is bookworm. Default ARCH is 64. The script expects corresponding
+$BASEFILE_DIR/${UPCASED_BASE_CODENAME}${ARCH}.tar.(zst|xz) to exist, and it must have been
generated around the same time as the nfsroot, at least so it has the
same kernel version.
