Default problem installing custom kernel

Hi,
I tried compiling and installing the linux kernel from ABS. I modified the
PKGBUILD file as mentioned in the wiki. The kernel compiles fine and the pkg
gets built with the name linux-custom as specified in the PKGBUILD. But when I
try to install it I get the following error:

$ sudo pacman -Uv linux-custom-3.2.2-1-x86_64.pkg.tar.xz
Root : /
Conf File : /etc/pacman.conf
DB Path : /var/lib/pacman/
Cache Dirs: /var/cache/pacman/pkg/
Lock File : /var/lib/pacman/db.lck
Log File : /var/log/pacman.log
GPG Dir : /etc/pacman.d/gnupg/
Targets : linux-custom-3.2.2-1-x86_64.pkg.tar.xz

looking for inter-conflicts...
:: linux-custom and linux are in conflict (kernel26). Remove linux? [y/N] N
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: linux-custom and linux are in conflict

I have attached the PKGBUILD.

That's you problem in the PKGBUILD. Your custom kernel doesn't need to
provide, conflict nor replace kernel26, as that is what causes it to
conflict with the Arch one

OK. I read the wiki page once more and found out my mistake. Since my kernel
has already been compiled can I create the package without compiling it again?

You can edit the .PKGINFO file directly that's within the .pkg.tar.xz. Also, you
should leave provides (even make it provides=('linux')) so that if you ever
want to remove the [core] kernel, you may do so.
