kernel make clean and backup

alphonsebrown · #1 27th March 2005, 03:07 PM

su root
uname -rm
make oldconfig
make all
drink coffee
make modules_install
make install # you may need to backup something now
# make clean
reboot

>> what do I have to backup actually?

make rpm maybe? but what kind of .rpmmacros do I need?

Hi,

if you do a "make clean" after each "make install" you have to backup the headers for your new kernel. As i usually have enough diskspace , i don't do a "make clean" after kernel installation (with "make install"), but i must admit, that this wasts some harddiskspace. And i suggest that you don't do a make clean until your new kernel is up and runing and perefctly tuned for you. Each reconfiguration will take much, MUCH more time if you allways clean up after installation!

Hope that helps.

Dorian

by the way: make rpm showed some errors... also first line of output was "make clean" ...

Ah, if you "cleaned" your sources before the "make rpm" there should be nothing left to make the rpm from. Hence you should get errors.

Note: It depends on the rpm-script, which is run for building the rpm for the kernel. Right now it seems -to my own surprise-, that by typing "make rpm" in vanilla kerenel-2.6.11.4 everything is redone. Therefore the "make clean" does not break the rpm building. I recall this not being the case with some prior kernels, but cant prove it right now.

But all may not be lost depending on how the kernel was built (CONFIG_IKCONFIG=y and CONFIG_IKCONFIG_PROC=y), check for the existance of the /proc/config.gz file. If this file exists while running the kernel you want to create an rpm for simply copy the expanded file (config) and rename the file to .config in the source directory and then use 'make rpm'

i didn't make clean just make rpm and not working :

what to do ? to make rpm from new kernel build?

dorian · #9 28th March 2005, 09:53 AM

Hi,

you kernel can be build using "make", or not? I don't build rpms for my kernel, so i am not of much help here. For me, as soon as "make" worked, "make rpm" worked too (as far as i tested it). I am not sure, but i was wondering why you use the i386 architecture, when your sig states that you have a athlon based system. Could that be the problem? Are you trying to build a kernel for an other computer on an athlon?

no I', building for my machine anfd it's currently i686 arch but I was wondering if it's applicable to make in target=athlon>? and propably will have then the rpms in athlon subfolder?
