/usr/src/linux/.config: questi

surfingbean

i learned that the configurations settled with i.e. menuconfig is stored in /usr/src/ linux/.config
so i guess the next steps: make dep, make bzImage...  will compile the kernel according to .config
if that is true, i just have to save several .config files as other names. and when i need one of them, i can just name it ".config" and compile it. consequently, i don't need settle the options by menuconfig.  can anyone comfirm?
thanks!!

yes, u are right. i remember that this should be ok.

确实是这样，不过，建议copy　.config前，先make mrproper,再copy，再make dep...

  forget to mention this. this can solve u much time when u meet big problems. but as i know, unless u change some improtant settings like smp support,  and if u only change some device setting, u can omit this step and save some time.

同意，如果先前编译过内核，现在要修改＋重新编译，只要你的内核配置相比以前的配置不是改动太离谱，直接make dep和make bzImage会省下很多时间，但有时可能会出错；如果真不幸出错了，只好先备份.config，先make mrproper，再恢复.config，再make dep完完全全重来一遍

nod, u give the final solution
