Test for docker cgroups issues in crunch-run works on ubuntu 20.04
the 2 options we have here is
1) Test with a single node arvados salt install and make sure that workflows run on ubuntu 20.04
2) have a compute image baked with 20.04 in one of our current clusters

Run the provision script on a virtual machine with ubuntu 20.04, using the ubuntu-dev repo. It passes OK because ubuntu 20.04 ships
systemd v45, which still uses
$ dpkg -l |grep systemd ... ii systemd 245.4-4ubuntu3.4 $ cat /sys/fs/cgroup/cgroup.controllers cat: /sys/fs/cgroup/cgroup.controllers: No such file or directory
and running the hasher workflow passes.

To verify with newer systemd, I updated ubuntu's
systemd package to 247.1-4ubuntu1, rebooted the instance and I found that it's still using
Searching around, it seems that, due to some regressions, Ubuntu reverts Debian's systemd changes and they will ship
cgroups v1 until 21.10.
So I'd say Arvados will be OK in ubuntu 20.04.
