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 did Linux From Scratch recently and they have a brilliant solution. Here's the full text but it's a long read so I'll briefly explain it. https://www.linuxfromscratch.org/hints/downloads/files/more_control_and_pkg_man.txt
Basically you make a new user with the name of the package you want to install. Login to that user then compile and install the package.
Now when you search for files owned by the user with the same name as the package you will find every file that package installed.
You can document that somewhere or just use the find command when you are ready to remove all files related to the package.
I didn't actually do this for my own LFS build so I have no further experience on the matter. I think it will eventually lead to dependency hell when two packages want to install the same file.
I guess flatpaks are better about keeping libraries separate but I'm not sure if they leave random files all over your hard drive the way apt remove/apt purge does. (Getting really annoyed about all the crud left in my home dir)
Thanks for the read. This is what I was thinking about trying but hadn't quite fleshed out yet. It is right on the edge of where I'm at in my learning curve. Perfect timing, thanks.
Do you have any advice when the packages are mostly python based instead of makefiles?
for python, a bunch of venvs should do it
