+# ubuntu notes
+
+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
+cd /b/fai
+# set 51-multi-boot to set classes outside of fai-wrapper conditional, including NOWIPE
+. fai-wrapper
+./fai/config/hooks/partition.DEFAULT
+
+# on remote host
+# install ubuntu 20.04 using virt-install
+sudo -i
+virt-install --os-variant=ubuntu16.04 --cdrom ubuntu-20.04-desktop-amd64.iso --disk path=u2004.qcow2 -r 2048 --vcpus 1 -n u2004
+qemu-img create -o preallocation=metadata -f qcow2 u2004.qcow2 15G
+# alternatively, also tried a physical install, because I know the virtual install ends up
+# with some differen things, like some spice service. then pulled the data out with
+rsync -ahSAX --numeric-ids --exclude=proc --exclude=sys --exclude=dev --exclude=tmp --exclude=run root@tp:/ .; mkdir proc sys dev tmp
+
+modprobe nbd
+qemu-nbd --connect=/dev/nbd0 u1804.qcow2 -f qcow2
