[3006.x] Docker systemd container identified as physical #67905
Description
Description
The virtual and virtual_subtype grains in a systemd based Docker container shows as "physical" instead of "container". This seems to be because /proc/1/cgroup no longer contains the docker strings, which is what we test for:
# cat /proc/1/cgroup
0::/
Similar issue to #67733
