It’s not really a big deal, but I am currently writing this using a linux kernel I compiled from source, which certainly feels like an accomplishment. The Arch Wiki has made the process fairly easy to follow. I just took the stock Arch Linux configuration without changes for now.
The most important part of this is of course that I have the option to do that, to take the source code of this incredible project and build my own kernel binary.
How long did it take to compile?
I didn’t really keep track, but I would estimate around 10-15 minutes on a Ryzen 5800X.
I compiled my first Linux kernel back in the mid 90s, mostly on 386 and Dec Alpha hardware, interesting enough both were not that much slower than what you mentioned, I think the alpha (a measly 21066) took about 40 minutes. If you had asked me back then, I’d probably have imagined a minute or two, 30 years later. Guess it says something about how much larger the Linux kernel has become.
