Kernel Compiling

[fuzzy]

I have successfully integrated a recent version of kernel 2.4 into my system but now want to make a few changes.
How far do I have to go?
I assume

make menuconfig (or xconfig)
make dep
make clean
make bzImage

But that's it right? I mean, since LILO is already pointing to the correct kernel, I don't need to worry about that anymore, or am I wrong?
(Oh, I suppose I should do a make modules and make modules_install, too, after make bzImage, right?)
TIA!

make menuconfig
make dep
make clean
make bzImage

make a backup of your old kernel:
cp /vmlinuz /vmlinuz_BACKUP

then assuming you are targeting x86:
cp /usr/src/linux/arch/i386/boot/bzImage /vmlinuz

then reinstall the boot loader so that it will know you have recompiled the kernel:
/sbin/lilo

If you've changed any modules you will also have to do:
make modules
make modules_install

Good Luck!

Thank you!
After installing and configuring the kernel, I realize I made some dumb choices and I can sense a significant drag in performance so I want to streamline it a bit by recompiling it.
Thanks.

i've made it a habit of running "make mrproprer (maybe its mbproper, i forget)" before "make config". it deletes stale.o files that you need to get rid of.

But 'make mrproper' also deletes your old kernel configuration (.config) so you have to select all the options again.

Yeah, that could be ugly.
I just want to make a few changes to my already-existing configuration.
make mrproper is good when you're starting with a fresh kernel install.
But I suppose copying my current /vmlinuz to /vmlinuz_old is good in case my "revisions" are more like "collisions", eh? http://www.linuxnewbie.org/ubb/smile.gif
Then, once I know the new configuration is good, rm the current one?
