I start with an empty /home/degenaro/.config/containers directory. 
I run podman info.
I see that files libpod.conf and storage.conf have been created.
I grep for "/home" and see:
libpod.conf:volume_path = "/home/degenaro/.local/share/containers/storage/volumes"
libpod.conf:static_dir = "/home/degenaro/.local/share/containers/storage/libpod"
storage.conf:  graphroot = "/home/degenaro/.local/share/containers/storage"

What's wanted is to configure podman so that "/home" is replaced by "/tmp".  That is, if I were to erase these .conf files and run podman info again I want to see:

ibpod.conf:volume_path = "/tmp/degenaro/.local/share/containers/storage/volumes"
libpod.conf:static_dir = "/tmp/degenaro/.local/share/containers/storage/libpod"
storage.conf:  graphroot = "/tmp/degenaro/.local/share/containers/storage"

The desire is to have all rootless users use /tmp instead of /home, since /home is on a shared filesystem which seems to be problematic for podman.

Thx.
