[pkg-go] Bug#1050993: podman: Podman should use overlay storage driver by default instead of vfs

[Gregor Riepl]

Package: podman
Version: 4.4.0+ds1-1
Severity: normal
Forwarded: https://github.com/containers/podman/issues/19811
X-Debbugs-Cc: onitake at gmail.com

The vfs storage driver in Podman has been the recommended upstream default up
until 4.4, but there isn't really a good reason to use it any more. The overlay
driver is faster and more conservative in most cases.

Please upgrade Podman to 4.5+ (4.6.3 is current) in Debian, or add the
configuration file /etc/containers/storage.conf with the following contents:

[storage]
driver = "overlay"

For reference, I ran into a serious storage explosion with the vfs driver
recently: https://github.com/containers/podman/issues/19811
This issue doesn't occur with the overlay driver.

Thanks!
