was trying to summarize the possibilities for config files: - mounts.conf - storage.conf - libpod.conf and ended up falling into a maze of twisty passages, all alike. (all this is based on packaged podman-1.7.0 on fedora 31). first, from "man podman", those three files are explained thusly: libpod.conf (/usr/share/containers/libpod.conf) libpod.conf is the configuration file for all tools using libpod to manage containers, when run as root. Administrators can override the defaults file by creating `/etc/containers/libpod.conf`. When Podman runs in rootless mode, the file `$HOME/.config/containers/libpod.conf` is created and replaces some fields in the system configuration file. mounts.conf (/usr/share/containers/mounts.conf) The mounts.conf file specifies volume mount directories that are automatically mounted inside containers when executing the `podman run` or `podman start` commands. Administrators can override the defaults file by creating `/etc/containers/mounts.conf`. When Podman runs in rootless mode, the file $HOME/.config/con‐ tainers/mounts.conf will override the default if it exists. Please refer to containers-mounts.conf(5) for further details. storage.conf (/etc/containers/storage.conf) storage.conf is the storage configuration file for all tools using containers/storage When Podman runs in rootless mode, the file `$HOME/.config/containers/storage.conf` is used instead of the system defaults. so the first inconsistency(?) is that the first two files have a possibly default version under /usr/share/containers, while storage.conf does not -- according to "man podman", the default file will be in /etc/containers. it's not clear why the inconsistency. the next oddity is that the first two files are contributed by two different fedora packages: $ rpm -qf /usr/share/containers/libpod.conf podman-1.7.0-2.fc31.x86_64 $ rpm -qf /usr/share/containers/mounts.conf containers-common-0.1.40-4.fc31.x86_64 that may not sound like a big deal but it does allow for some inconsistency in how those two packages either supply or explain things, which is what you see when you "man containers-storage.conf": Distributions often provide a /usr/share/containers/stor‐ age.conf file to define default storage configuration. Adminis‐ trators can override this file by creating /etc/contain‐ ers/storage.conf to specify their own configuration. The stor‐ age.conf file for rootless users is stored in the $HOME/.con‐ fig/containers/storage.conf file. so "man podman" does *not* mention the possibility of /usr/share/containers/storage.conf, while "man containers-storage.conf" *does*. finally, i thought, "oh, just RTFS" to see what is really happening, and in libpod/config/config.go (amd i am *not* a go expert), it seems like libpod.conf is supported being under /usr/share/containers, but i don't see where the other two files (mounts.conf, storage.conf) are similarly supported, although i could be just misreading badly. i'm just trying to clarify the configuration file possibilities. rday
