convert from MBR to GPT. I understand GPT is more convenient,

As an exercise for the future for some OSs to use > 2TB fair enough but if your doing it for convenience, please explain because MBR has become a proper well tested cross platform standard and GPT won't according to a recent thread on the OpenBSD list. ________________________________________________________ Why not do something good every day and install BOINC. ________________________________________________________

I think that you will not find this one. The best explanation of most of these submenus (that I know of) is the help text that accompanies them. Other than the kernel source of course! That said, there are quite a few options that are well documented elsewhere... just google for them if they seem interesting enough. I would start by setting in-kernel all the modules your kernel loads at start up. The objective would be that in a fully booted system, the command "lsmod" returns nothing. That will keep you busy for quite some time ;-P After that you can start removing all the modules for weird hardware you don't have or will foreseeable have, in order to reduce the compilation time. And then... without even noticing, you will have learned a lot about even the most arcane kernel options... -- Rodrigo

Sounds good. I will then stick to your approach, as it makes sense.

personally i would use the kernels `localmodconfig`, ie. `make localmodconfig`. this make target will build a kernel matching the current state of your system. so, you must: 1) boot normally 2) `modprobe -r` any modules you *for sure* don't need 2) `modprobe`/launch absolutely every module/application you might want or need (everything! loopback, bluetooth, etc) 3) `make localmodconfig` ... this will build you a kernel with only the bare minimum needed to fulfill your current state; any modules not loaded at this time will not be built. you may still need to configure other features unrelated to modules. -- C Anthony

Anyway, is a kernel configuration and (re)compilation really worth the pain and time ??

Is a custom kernel giving any benefit or speed-up apart from something marginal and more about the feeling than anything else ?

I gave up trying to make one just by lazyness on archlinux. I did that many years when I used slackware.

But that's a thing to do at least once in a lifetime of course :-)

The advantage of having a kernel with more than what is needed is, that it's easier to change hardware if needed. I don't reduce the sizes of my kernels, the drawback is, that it takes around 90 minutes to compile a kernel on an AMD dual-core 2.1GHz, 4GB RAM, 2 jobs. Regarding to the used size or performance IMO it's useless to reduce the kernel's contend, simply don't load unneeded modules. IIRC the OP wishes to learn, IOW he'll do this as an exercise.

We can dream for comprehensive. I presume you know about uncommenting in PKGBUILD and/or using the new nconfig or xconfig and the search functions etc.. You still have to hope Google can answer what you are wondering and hopefully that your not just wandering. ________________________________________________________ Why not do something good every day and install BOINC. ________________________________________________________

nconfig has this nice option (in the old menuconfig too, just don't remember the button in there) to press the F2 button, to display a short description of the option. (Not all do have one but most.) Usually there is also a small note at the bottom of the description saying "If you don't know what this is you can probably say n here" (n meaning no, do not build this feature), there is also another one, which is basically the same, but is tells to enable the option instead.

Good enough as for the Kernel and TY for the tips. As for my separate /usr, is it safe to move it back to system root, or better stay like that considering my nox is running smoothly?
