about storage.conf

[fantastic2085]

I installed podman in ubuntu22.04 and compared it to Podman-static

1. Why is ignore_chown_errors set to true
2. Why set fsync=0 for mountopt
3. Why is mount_program not commented out

Can I modify it as follows:
#ignore_chown_errors = "false"
#mount_program = "/usr/bin/fuse-overlayfs"
mountopt = "nodev,metacopy=on"

Except for the containers.conf, all configuration files are used for both images shipped by this repository: the rootful/normal podman container and the rootless/minimal podman container. That's why the configuration is optimized for rootless podman. Also, I must admit I didn't touch the configuration files for a long time during updates. Regarding your questions:

1. If I remember correctly, this was necessary to make rootless podman work (at least at the time of writing). For rootful podman that is not necessary.
2. I don't know for sure. I may have copied that from an old podman version or it was also because of an issue with rootless podman at the time.
3. I also did that to make rootless podman work (overlayfs is implemented within the kernel space and the best user-space alternative is fuse-overlayfs).

A rootful podman should work with your config changes.
