I'm so new at this (first time around doing LFS on my home computer) that I'm not sure I'm asking the right questions. So here's a bit more: The BLFS doc says to do some reconfiguring (which modifies the .config file) and then to "recompile the kernel *if necessary*". This implies to me that some modifications to the .config file will NOT require recompilation, while others will. So guess my questions should have been, What modifications DO or DO NOT necessitate recompilation? And where can I find documentation to educate myself thoroughly about this stuff? The documentation I've read so far gives one all manner of choices, but newbies are probably not yet smart enough to know what's what with the choices. So we need some hand holding. Thanks for all your answers! I'll be attacking this again tonight when I get home from work.
