[NFBCS] Keeping Linux Tidy

Sat Apr 3 01:22:34 UTC 2021

Do any of you make use of a sandbox to Test accessibility of applications or keep things clean?I am not sure if this would work with things that need to be installed, but I believe that in theory this would definitely work with things such as scripts or apps that don’t need a full install with, “make” and “make install”.An example of what I mean is by using something called fire jail. You can run things in firejail and have associated files put in a temporary folder that disappears at boot.

My thinking is that I could use this to create a bash alias such as, “sandbox app_name” and then I could create a designated folder for the application and move the files there if it is accessible and some thing I actually want to keep. If it is not accessible or something I don’t really want on my machine, then it will be gone after a restart anyway. If it is something I actually want to keep, I would just run it without fire jail.

Thoughts on doing this or any issues if I did it this way?
