Hi All,
I installed the kernel 2.6.36 into my Fedora 12 system.
I am now low on disk space.
[root at rishi-desktop kernels]# du -sh linux-2.6.36/
4.4G linux-2.6.36/
It shows that the new compiled kernel is taking around 4.4GB.
The /lib/modules/2.6.36 is taking around 780M on my disk.
I wanted to free some of the space occupied by the compiled code. I
understand that the /lib/modules/2.6.36 directory can't be deleted as it
contains the compiled modules.
I wanted to delete the files in /usr/src/kernel/2.6.36, without effecting my
newly installed kernel.
-> Can I delete them?
-> What is the best way to delete them, I want to keep the source files?
-> Should I run make clean to remove the compiled code?
-> Any other way?

Regards,
Rishi Agrawal

Hm, I think that's rather big....here after compilation (of course, my
.config is likely different than yours), 2.6.36 takes approximately
1.7 GiB

Together with the object files during linking stage, I believe :)

Yup...

AFAIK, /lib/modules/<version>/build is symlink-ed to that source code
dir, so IMHO don't delete it..

I think the best way here is to do "make clean" and then followed by
"make modules_prepare". That way, your kernel source dir is build with
files enough to compile external modules whenever needed, but not too
bloated

Hi Rishi,
One other thing that might help is not compiling a debug build if you
dont need it. Debug objects are much bigger of course. If you're ending
up at 4.4GB it sounds like a build with debugging on.

yes I have some debugging options set.
The current usage (after make clean and modules_prepare ) is around 867M.
Thanks a lot...
