In normal use, the only issue is that these empty directories can be created wherever the user has write permissions. However, if `-mirror-screenshots-url` is specified, then flatpak-builder will launch `flatpak build -nofilesystem=host appstream-utils mirror-screenshots` after finalization, which can lead to issues even with the `-nofilesystem=host` protection. Normally this will not be done, so this is not problem. ![]() At this point the build directory will have the full access that is specified in the manifest, so running `flatpak build` against it will gain those permissions. flatpak-builder applies `finish-args` last in the build.
