Been using Gentoo on my server for over a decade now and probably won’t ever leave the compiling front, especially with a 12-core/24-thread CPU making it go as quick as regular binary updates on my mint laptop… But that being said, in happy to see them considering to do this. It’ll bring in some folks who are afraid of (or just dislike) compiling everything from source. I think the biggest packages that’d benefit from this are definitely the browsers and desktop environments.
This is what I use. The project is dead and had some bugs that kept it running on my system right away, but as it’s open source, I was able to fix the code a little bit to success. Just wish it was a little friendlier on cpu or could be selective on which apps to run instead of recording nonstop regardless. I have it start up with Steam for now though.
