Comment 15 for bug 1880211

Verified this in in xenial, bionic, and focal in LXC. I needed to adapt the test case for each distro due to changes in zfs behavior on each:

  - On xenial, can run the test case as-is, via 'apt-get install zfs'
  - On bionic, must instead install 'apt-get install zfsutils-linux', but otherwise works ok
  - On focal, installing zfsutils-linux in lxc results in a failure regarding the service not starting, however the zfs tool itself is installed in the expected place, so for purposes of this SRU is verified.
