So
| Before upgrade to 4.4.0+ds1-1 (4.3) | 4.4.0+
/etc/containers/strorage.conf | use btrfs | btrfs
/usr/share/containers/storage.conf | use
overlayfs | overlayfs
----
When use 4.3, podman takes /etc/containers/storage.conf, so the storage
is btrfs.
But after upgrade 4.4.0+ (at least when it was April).
Podman takes values in /usr/share/containers/storage.conf instead of
/etc/containers/strorage.conf (wrong behavior)
So just get the following
User-selected graph driver \"overlay\" overwritten by graph driver \"btrfs\"
from database
That is the observed error. But not expected error.
The expected behavior is
Podman follows man 5 containers-storage.conf.
Prefer values from /etc/containers/storage.conf.
After version upgrade from 4.3 to 4.4, no configuration required, no
reset required.

But in 4.4.0+ds1-1. with both files, podman takes the config from
/usr/share/containers/stroage.conf
To reproduce this
Create podman graph database on podman 4.3.1 with btrfs (config in
/etc/containers/storage.conf)
upgrade from 4.3.1 to 4.4.0
run the following command
sudo podman info
expected error message
User-selected graph driver \"overlay\" overwritten by graph driver \"btrfs\"
from database
I'm not sure I follow. Could you elaborate on the exact steps you took?
Do you mean that you expected to get this error message but didn't, or
that you got that error message even though you shouldn't have?
Are you aware that you need to run "podman system reset" before changing
storage.conf? See podman-system-reset(1).
Thanks,
Faidon
