Bruh, I am pretty sure when I commented the question, this information wasn’t there.

Is there a way to see previous edits of a comment in fediverse?

Edit: Nvm I didnt read properly

What about app data? If I only want to backup my app data for all flatpak application but not the application itself, where can I find the directory?

Really cool bro. Always loved GUI for command line utils!

Openness of linux would be lost

Although device drivers are proprietary, linux does its best to limit such proprietry stuff. But in case of android, Google pretty much has a monopoly because a standard build of android isnt enough for use.

I hate the spirit of openness is shot on the foot just because of the need of commercialization. I would prefer linux than android.

Thanks for response!

Well not every app is in flatpak. Like steam gives you a .deb to download and not a flatpak. Only for this reason I said “dont say about flatpak”. I would definetly use flatpak where ever possible. I was simply asking for help in linux permsions and users in case I cant run app in flatpak. It isn’t a vague desire for “plain old linux” but instead a desire for when flatpaks arent possible, I need to do the same for it with plain linux.

But now I understand that these tools I mentioned arent really plain linux like I thought. I should have asked the question properly Also I didnt know firejail was like flatpak though.

So I now understand what to ask exactly.

I want to learn underlying tools which apps like flatpak and firejail use. Mainly the user permssions and filesystem permissions. Dont want to learn the application themseleves but want to do myself what these applications do in behind the scenes.

Thanks for the sources though!

Kind of looks like windows vista design. Also it is probably a best thing that linux be adopted by countries. Gives better control and can be used for variety of purposes

I have heard a lot of this apparmor but don’t know anything about it. I know the name explains it, but what is it exactly? What does it do?

Also you say as if creating profiles and users are different? Isn’t creating user accounts same as creating a new profile in linux, or am I confusing with profiles which are in apparmor?

Would appreciate some articles and tutorials regarding apparmor

Kernel based security packages profiles? What is that?
