I assume it doesn't, but thought I'd ask.
I really like the principles behind both gentoo and flatpak, but right now I can only do the gentoo way or the flatpak way (and I've opted for gentoo's for now).
What I'd love to have from flatpak:
- container like sandboxing and isolation
- customizable sandboxing and permissions
What I'd love to have from gentoo:
- powerful build system building packages from source
- global declarative management of compilation options
- easy patches
- easy to add packages that aren't in repos
- support for many architectures or setups
Build everything you use in podman or lxc
Build everything you use and ackage it in flatpak?
It's not even that hard to build your own gentoo-based runtimes and install stuff on top of that. Fedora does offer that, too, offering fatpaks based on their own fedora based runtime + rpms.
From my understanding this doesn't work too well for GUIs
