Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind feature

Description

Fedora 32, podman-1.9.3-1.fc32.x86_64
/etc/containers/storage.conf contains
driver = "overlay"

To use the btrfs driver, it's necessary to modify that, or create ~/.config/containers/storage.conf with the driver set to btrfs. Feature request is to use the btrfs driver if the file system is btrfs; and fallback to overlayfs otherwise.

Describe the results you received:

podman uses overlayfs driver by default when ~/ is on btrfs

Describe the results you expected:

podman uses btrfs driver by default when ~/ is on btrfs

Additional information you deem important (e.g. issue happens only occasionally):
