Re: [gentoo-user] a11y kernel build

[Jack]

Ah - a11y sort of like i18n and l10n (at least in how to read it.)   I  
just found a web page calling it a numeronym.

After all your reading, I would still suggest thinking carefully about  
your goal.  The link Peter sent has a good summary of all the "make Xc  
onfig" options, and I agree with him that "make localmodconfig" sounds  
like what you want.  Extra "Y" or "M" in your config might save you  
from recompiling the kernel again later, but it makes your kernel  
larger, and take longer to compile and load, although how much those  
delays bother you is very personal.
