 For flidas, when installing systemd, this error happens, and it's

+For someone who really needed ubuntu on host tp, otherwise they would
+end up on a non-gnu os, and I didn't want to figure out how to get all
+the default software installed, I did the following:

+# On remote host:
+# install etiona

+# set 51-multi-boot to set classes outside of fai-wrapper conditional, including NOWIPE
