hi i am trying to install the new kernel on my system.. some one told me that one should not install the kernel in /usr/src/linux coz kernel version that the C library is compiled against is often linked to this tree... what does this mean ... and
what is the difference between installation and compilation of the kernel...
when you do a "make" you can say that you have just compiled a kernel now you have the kernel image & the modules object files when you do "make modules_install" the modules are copied to the /lib/modules/<kernel version>/ & usually the kernel image is copied to /boot & the bootloader configuration file updated These last two steps means you have installed the kernel now you can see an option in the bootloader & boot the newly installed kernel
where should i install my kernel if i want to make changes to it and try to hack it...
usually its recomended to do all the kernel hacking from your home directory & sudo while installing
and if i install it somewhere other than /usr/src/linux... will there not be 2 kernels installed in my system..
no only make sure you don;t overwrite the existing one you can keep as many kernels in the boot directory just by giving them different names convention is /boot/vmlinuz-2.6.xx about the modules in /lib/modules/2.6.xx The top makefile has EXTRAVERSION = if you leave it blank a directory named /lib/modules/2.6.xx will be created when you do a modules_install if you want the same kernel version with some other configuration just do EXTRAVERSION =custom modules_install will work in /lib/modules/2.6.xx-custom
this thing is very confusing to me.. will greately appriciate if some one can demystify this thing to me..
you should consider yourself lucky coz now we have Linux Kernel in a Nutshell http://www.kroah.com/log/linux/lkn.html -- Milind Arun Choudhary -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
