Support for installing apps from USB drives
Here’s an initial attempt at upstreaming the code we have in EOS for installing apps from USB drives. It’s been moderately tested, but would need more testing before being merged.
It can install flatpak apps from a USB drive created with
flatpak create-usb as long as the relevant flatpak remote is set up to enable P2P.
It was mostly written by @jrocha, with some tweaks and rearrangement done by me when rebasing it for upstreaming.
