This page describes how to use a non-Funtoo, unofficial kernel. For official Funtoo Linux kernels, see Funtoo Linux Kernels.
This HOWTO will show you how to get a RHEL6 kernel running on a Funtoo Linux system.
Step 1: Dependencies
In kernel.spec from kernel-2.6.32-71.18.2.el6.src.rpm say:
# grep BuildRequires kernel.spec BuildRequires: module-init-tools, patch >= 2.5.4, bash >= 2.03, sh-utils, tar BuildRequires: bzip2, findutils, gzip, m4, perl, make >= 3.78, diffutils, gawk BuildRequires: gcc >= 3.4.2, binutils >= 2.12, redhat-rpm-config BuildRequires: net-tools, patchutils, rpm-build >= 4.8.0-7 BuildRequires: xmlto BuildRequires: asciidoc BuildRequires: sparse >= 0.4.1 BuildRequires: elfutils-libelf-devel zlib-devel binutils-devel BuildRequires: gnupg BuildRequires: python BuildRequires: hmaccalc BuildRequires: glibc-static # grep BuildConflicts kernel.spec BuildConflicts: rhbuildsys(DiskFree) < 7Gb
It is advised to update sys-fs/udev sys-fs/lvm2 and sys-devel/gcc if they are not at their latest revision:
# emerge -1 sys-fs/udev sys-fs/lvm2 sys-devel/gcc These are the packages that would be merged, in order: Calculating dependencies ... done! [ebuild R ] sys-devel/gcc-4.4.5 USE="fortran mudflap (multilib) nls nptl openmp (-altivec) -bootstrap -build -doc (-fixed-point) -gcj -graphite -gtk (-hardened) (-libffi) -multislot (-n32) (-n64) -nocxx -nopie -nossp -objc -objc++ -objc-gc -test -vanilla" 0 kB [ebuild R ] sys-fs/udev-160-r1 USE="extras (-selinux)" 0 kB [ebuild R ] sys-fs/lvm2-2.02.75 USE="rc_enable" 0 kB Total: 3 packages (3 reinstalls), Size of downloads: 0 kB
Step 2: Install kernel sources
The process for installing an RHEL6 kernel has been drastically simplified. Simply perform the following steps:
# emerge -av layman && layman -a init6;
Or copy the ebuild `s yourself from github.
# emerge sys-kernel/rh-sources
This step is to download the latest src.rpm (at the time of writing this page is kernel-2.6.32-71.18.2.el6.src.rpm) uncompresses the source code and will put some patches:
xfs-list-sort.patch say thx damex from #funtoo channel on FreeNode irc net.
font-8x16-iso-latin-1.patch this patch replaces the font font-8x16 from the linux kernel to a more pleasant and beautiful font was created by Mr. Ka-Ping Yee. Appearance of the font can be seen here Ka-Ping Yee ISO Latin-1 Font in linux kernel
To use this font enable
-> Device Drivers -> Graphics support -> Console display driver support -> Select compiled-in fonts (FONTS [=y]) [*] VGA 8x16 font
or simply enable CONFIG_FONT_8x16 in kernel config.
I have not tested "Module ELF structure verification" CONFIG_MODULE_VERIFY_ELF, "Module signature verification" CONFIG_MODULE_SIG everything besides including the nvidia-drivers, nouveau, broadcom-sta works fine.
Step 3: Build it
Build it as you build any other kernel. There is nothing extraordinary. No special startup options in the grub is required. That's all kids ;) And may the source/force be with you.
