Adapted from: https://github.com/flatpak/flatpak/pull/6125 In systemd v259, /run/host/root will be a documented location for bind mounting the host's root filesystem into a container. Ref: https://github.com/systemd/systemd/pull/38384 host-root is the sledgehammer permission for file browsers and similar apps that the user might want to give full access to. This works same as the existing host keywords by mounting into /run/host/root. applications will need adjustments to essentially treat that path as "root". Since this opens the door to all sorts of malicious software, the permission should be put under tight review in flatpak repositories.

The sdk that is specified in the <filename>metadata</filename> file

respectively. They are writable, and their contents are preserved between

build commands, to allow accumulating build artifacts there.
