Project mention: Sandboxing All the Things with Flatpak and BubbleBox | news.ycombinator.com | 2024-04-14

If anyone want to look further into sandboxing applications on Linux, you can also look at AppArmor and the sandboxing features built into systemd.
I love this repository for bases for AppArmor profiles[1], really good work. Never found a repository as good for systemd, but there are a few around.
