When running in a rootless container (made possible via osbuild/bootc-image-builder#1189) then generally the per-user container store is passed to bc-i-b, both because that makes sense, but also because the container doesn't have permissions to read the host store. This is typically done by passing `-v ~/.local/share/containers/storage:/var/lib/containers/storage` when running bc-i-b in podman. Unfortunately when this happens, podman complains that the store is in the wrong place: ``` Error: database static dir "/home/alex/.local/share/containers/storage/libpod" does not match our static dir "/var/lib/containers/storage/libpod": database configuration mismatch ``` To fix this, we pass in podman arguments `--root` and `--imagestore` to set up an environment where the graphroot is some empty directory that has the "correct" location and we only load the image layers from /var/lib/containers. To ensure this doesn't weirdly affect the regular case, this is all protected by podmanutil.IsRootless().

When running in a rootless container (made possible via osbuild/bootc-image-builder#1189) then generally the per-user container store is passed to bc-i-b, both because that makes sense, but also because the container doesn't have permissions to read the host store. This is typically done by passing `-v ~/.local/share/containers/storage:/var/lib/containers/storage` when running bc-i-b in podman. Unfortunately when this happens, podman complains that the store is in the wrong place: ``` Error: database static dir "/home/alex/.local/share/containers/storage/libpod" does not match our static dir "/var/lib/containers/storage/libpod": database configuration mismatch ``` To fix this, we pass in podman arguments `--root` and `--imagestore` to set up an environment where the graphroot is some empty directory that has the "correct" location and we only load the image layers from /var/lib/containers. To ensure this doesn't weirdly affect the regular case, this is all protected by podmanutil.IsRootless(). Note: This is similar to what is done in osbuild/image-builder-cli#447 and it has a local copy of podmanutil.IsRootless() from image-builder-cli.
