With the move to crun instead of runc for the container engine, we seem
to hit a known issue that was corrected back in 2015[1] for runc. There
was then a regression, fixed with [2] a bit later.
There's a good chance crun has a partial fix only, matching only /dev
and not /dev/, leading to the change of /dev/ptmx from an actual node to
a symlink pointing to /dev/pts/ptmx.
Another fix might be ensuring we don't have any trailing "/" in the
volume paths passed to the tripleo-ansible/tripleo_container_manage
module/role.
