I followed Mental Outlaw’s 2019 guide and followed the official handbook to get up-to-date instructions and tailored instructions for my system, the process took about 4 hours however I did go out for a nice walk while my kernel was compiling. Overall I enjoyed the process and learnt a lot about the Linux kernel while doing it.
I’m planning on installing it to my hardware soon, this was to get a feel for the process in a non-destructive way.
What is the value proposition of Gentoo over, say, something like NixOS?
Actual USE flags I guess? If you ultimately want these is a different question though
USE flags and profiles.
I have one old laptop where I decided to test some more obscure Gentoo setups. I chose musl as libc and took llvm toolchain to compile stuff. (All experimental)
Interesting, looked at the Gentoo docs to understand USE flags. Nix has similar capabilities, where some packages expose configuration options that apply to the build, but it’s not a overtly named feature consistently applies across all packages. It seems that something like USE flags could be implemented rather easily by Nix but was either deemed not necessary or was an oversight. You can still change the build for any package but it might involve introspecting the package definition to figure out what to change so not meant as a first class mechanism like USE flags.
Edit: found this: https://github.com/NixOS/nixpkgs/issues/12877
USE flags have some inherent “issues” or rather downsides that make them non-options for some distributions.
First, they create a much larger number of package variants, simplified 2^(number of USE flags applicable to package). This is fine if you don’t want to supply binaries to your users. Second, the gain they bring to the average workstation is rather insignificant today. Users usually want all functionality available and not save 30 kb of RAM and then suddenly have to rebuild world because they find out they’re missing a USE flag that they suddenly need. Also, providing any kind of support for a system where the user doesn’t run the binaries you provided and maybe even changed dependencies (e.g. libressl instead of openssl) is probably impossible.
It’s very cool stuff if you want to build a system very specific to your needs and hardware, and I do believe that NixOS could have profited in some parts from it, but I don’t have specific ideas.
Everyone should do this at least once
Agreed. It’s such a great learning process. I ultimately gave up on Gentoo but learned a lot by using it for about 2 years way back in around 2005.
Linux From Scratch brings a huge leap in understanding too.
Dont want to offend, but this is the most environmentally harmful OS on this planet probably. Except maybe BitcoinOS or something XD
Might as well call linux the most polluting OS. It props up old inefficient systems with high TPW and takes longer to complete tasks. Whereas microsoft and apple makes sure their users are on the latest efficient hw. Maybe a bit offset by the ewaste but who cares, Apple and MS are out savingy the earth.
To show how moronic your claim was to term it as “most environmentally harmful OS” on one single factor(cpu time).
