From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I linked the source but sure, I'll link it more for you.
The portal code is here: https://github.com/refi64/zypak/blob/ded79a2f8a509adc21834b95a9892073d4a91fdc/src/dbus/flatpak_portal_proxy.h
The actual code that Chromium calls is here: https://github.com/refi64/zypak/blob/ded79a2f8a509adc21834b95a9892073d4a91fdc/src/helper/spawn_latest.cc#L21
This calls the
org.freedesktop.portal.Flatpak
service.This service is here: https://github.com/flatpak/flatpak/tree/main/portal
The
Spawn
method creates a new sandbox completely isolated from the originating sandbox.I am aware, but the same source seemingly contradicted your point^[1]^ regarding sub-sandboxing.
Wow, thanks a lot for the work you've put into this! It might take some time for me to go through this, but I'll definitely take a look and perhaps I'll return on this at a later point. Perhaps with this I will finally be able to install my Chromium-based browsers as a flatpak and don't feel bad about it.
Once again, your engagement has been much appreciated! So please feel free to let me know if I can buy you a coffee or something 😊! Unfortunately, statements like "Thank you so much!" don't quite capture the sheer magnitude of gratitude I feel towards you right now. For whatever it's worth; I salute you, good human.
The comment on there is odd, I’m not even sure what that issue is referring to. Not much exciting happened in that release for new features but there were subsandbox security fixes https://github.com/flatpak/flatpak/compare/1.10.8...1.12.0
Thanks for taking the time to take a proper look at the link!
