As predicted, we're starting to see flakes in CI due to podman-remote tests being enabled. This one manifests as:

$ [some podman command]
[+0242s] # read unixpacket @->/var/run/libpod/socket/99a264c5e5fcaed668d0413741c63bfb90bdcdb02e1ad4ad109d7f6fe064fd84/attach: read: connection reset by peer

Seen in special testing rootless in #7224

Seen in fedora 31 test in #7222

I'm sorry not to be able to provide more information. I tried to reproduce this one last week and was unable to.
