Currently the CIDFile is not removed with podman --remote run --rm
if the client and server are on different machines.
[NO NEW TESTS NEEDED] i
There is currently a test for this that does not fail because the client
and server are on the same machine.
If we run these tests on a MAC or Windows platform, they would start
failing.

The original SELinux support in Docker and Podman does not follow the
default SELinux rules for how label transitions are supposed to be
handled. Containers always switch their user and role to
system_u:system_r, rather then maintain the collers user and role.
For example
unconfined_u:unconfined_r:container_t:s0:c1,c2
Advanced SELinux administrators want to confine users but still allow
them to create containers from their role, but not allow them to launch
a privileged container like spc_t.
This means if a user running as
container_user_u:container_user_r:container_user_t:s0
Ran a container they would get
container_user_u:container_user_r:container_t:s0:c1,c2
If they run a privileged container they would run it with:
container_user_u:container_user_r:container_user_t:s0
If they want to force the label they would get an error
podman run --security-opt label=type:spc_t ...
Should fail. Because the container_user_r can not run with the spc_t.
SELinux rules would also prevent the user from forcing system_u user and
the sytem_r role.

The intention of --read-only-tmpfs=fals when in --read-only mode was to
not allow any processes inside of the container to write content
anywhere, unless the caller also specified a volume or a tmpfs. Having
/dev and /dev/shm writable breaks this assumption.

Lock the VM on start. If the machine is in the "starting" state we know
that a previous start has failed and guide the user into resolving the
issue.
Concurrent starts will busy wait and return the expected "already
running" error.
NOTE: this change is only looking at the start issue (#18662). Other
commands such as stop and update should also lock and will be updated
in a future change. I expect the underlying issue to apply to all
machine providers, not only QEMU. It's desirable to aim for extending
the machine interface to also allow to `Lock()` and `Unlock()`. After
acquiring the lock, the VM should automatically be reloaded/updated.

HPC Community asked for this support specifically for using GPUs
within containers. Nvidia requires the correct shared library to
to be present in the directory that matches the device mounted
into the container. These libraries have random suffixes based
on versions of the installed libraries on the host.
podman run --mount type=glob:src=/usr/lib64/nvidia\*:ro=true. This helps
quadlets be more portable for this use case.
