point #2 my vng does have an overlayfs mounted over /tmp so the
mountpoint check doesn't trigger IDK if this is what you meant 
or I have a different version.  

I did try using --overlay-rwdir, and I think that gives rw to the
guest, but it's ro to the host, so we dont get to keep the pcaps post
mortem.

What we can do, if it sounds ok to you, is set up a temp scratch area
in the rds_logs folder so it's not mounting over /tmp, and then
run.sh can handle the mount with a cleanup trap addressing Sashiko's
concern

Let me know what you think?

Oh, you need these files for a post mortem analysis? I missed that
point. IDK if there's a well established way to save extra debug info
from the tests. runner has per_test_log_dir but I don't think it's
exposed to tests? Until ksft has such a thing I'd probably go with
an extra env variable to point the test to a specific dir.
Which dir will depend on the CI harness. If var is not set - don't
output the logs or use /tmp and clean up when test exits.

Ok, I will see if I can do some refactoring and pull the log dir out
of the test scripts and into an environment variable.  I think that
should work if I adopt the $SUDO_USER pattern the other tests use.

Thank you for the reviews!
