# Initial setup of a fai server on debian. works on localhost.
# Set's the current ip as the tftp server. I vaguely remember
-# that using a hostname does not work
-# Requires changing dns to point faiserver and running fai-redep
+# that using a hostname does not work.
+# Separate from running this, faiserver needs to be setup in dns
+# to point to whatever host this is run on.
