First install fedpkg from the fedora epel repo

CODE

su
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
yum install fedpkg

You will probably need to install and setup the required build tools as well

CODE

su
yum groupinstall "Development tools"

Setup your rpmbuild directory, as non-root run

CODE

cd ~
rpmdev-setuptree

as non root check out and build newt needed for rebuilding the newer kernels.

CODE

mkdir ~/fedpkg_checkout;cd fedpkg_checkout
fedpkg co -a -B newt
cd newt/f15
fedpkg srpm
su -c "yum-builddep -y newt-*.src.rpm"
rpmbuild --rebuild newt-*.src.rpm
su -c "yum -y --nogpgcheck install $HOME/rpmbuild/RPMS/`uname -m`/newt*rpm -x newt-debuginfo,newt-static"

Now for the kernel build (Takes 10 - 60 minutes to complete depending on hardware) (I have chosen the F15 kernel which is currently 2.6.38.3).

CODE

cd ~/fedpkg_checkout
fedpkg co -a -B kernel
cd kernel/f15
make release
fedpkg srpm
su -c "yum-builddep -y kernel-*.src.rpm"
time rpmbuild --rebuild --with baseonly --without debuginfo --target=`uname -m` kernel-*.src.rpm

If it completes successfully you will find the packages (kernel,kernel-devel,kernel-headers and perf) at ~/rpmbuild/RPMS/`uname -m`/

You can use fedpkg to build any package in the fedora and epel repos

If you have the required build requirements already installed you could run

CODE

fedpkg co -a -B whatever_packagename
cd whatever_packagename/f15
fedpkg local

to build

I will need to do a guide on rebuilding the kmods next

Besides that everything went great and it was as simple as copy/paste. Great How To, Thank you, EDIT: Thanks for putting time in the command to remind me how slow my build-system is. real 29m53.583s user 55m33.318s sys 12m6.579s

Hello leigh,

Besides that everything went great and it was as simple as copy/past.

Great How To, Thank you,

Thanks, I have changed it to

CODE

su -c "yum -y --nogpgcheck install $HOME/rpmbuild/RPMS/`uname -m`/newt*rpm -x newt-debuginfo,newt-static"

It all worked perfectly, installed perfectly and booted perfectly, even lsmod showed that all the blacklisted modules that I have personally blacklisted on my machine were still blacklisted. What an easy way to do a kernel upgrade! Thank you again, I am a big fan of your work (Thanks for the Firefox5 package as well). Best regards, Alex

One advantage of fedpkg is, you don't have to hunt down srpms.

Very interesting, but i've one question - is it possible to browse the Fedora repos from the command line somehow? I built python3 but just guessed at the name, which luckily worked (ie "fedpkg co -a -B python3").
