Tux Machines (TM)-specific
About a year ago I made some notes about plucking out parts of the 18.104.22.168 kernel — as well as some other ideas — with a goal of knocking down the boot time on an eight-year-old 550Mhz Celeron to about 16 seconds from Grub to X. I’ve configured a lot of kernels for a variety of machines in that time, and I have a few more subtractions to recommend.
I have the same disclaimers as last time.
* This is not a beginner’s task.
* You should be able to do everything described in the Crux Handbook before you try this.
* Do not copy and paste into your system. I am 99 percent sure your computer won’t even boot.
The good news is, depending on your hardware, core functions like graphics and networking rely only a few settings scattered here and there. You can reasonably get by without needing to leave in a whole lot.
