System tests: cover gaps from the last month
Browse files Browse the repository at this point in the history
- stop: test --all and --ignore (containers#9051)
- build: test /run/secrets (containers#8679, but see below)
- sensitive mount points: deal with 'stat' failures
- selinux: confirm useful diagnostics on unknown labels (containers#8946)

The 'build' test is intended as a fix for containers#8679, in which
'podman build' does not mount secrets from mounts.conf.
Unfortunately, as of this writing, 'podman build' does
not pass the --default-mounts-file option to buildah,
so there's no reasonable way to test this path. Still,
we can at least confirm /run/secrets on 'podman run'.

The /sys thing is related to containers#8949: RHEL8, rootless, cgroups v1.
It's just a workaround to get gating tests to pass on RHEL.
