DEPENDANCIES:
|
|
- GCC and binutils
|
|
- GNU Bash
|
|
|
|
USAGE:
|
|
See http://www.gentoo.org/doc/en/genkernel.xml or
|
|
issue ``genkernel --help''.
|
|
|
|
PORTING:
|
|
To port to other arches:
|
|
|
|
# cd /usr/share/genkernel
|
|
# cp -Rp x86 ${myarch}
|
|
# mkdir /usr/share/genkernel/pkg/${myarch}
|
|
|
|
Modify what is needed in the /usr/share/genkernel/${myarch}
|
|
directory, as well making a generic kernel-config.
|
|
|
|
IMPORTANT KERNEL NOTES:
|
|
- You MUST have /dev/pts turned on.
|
|
- If you want Bootsplash, you MUST have VESAFB enabled for 2.6,
|
|
other framebuffers won't work. You MUST also enable
|
|
"video mode selection support" and "Framebuffer Console support"
|
|
- From gentoo-dev-sources-2.6.8 and above, bootsplash has been replaced
|
|
with gensplash. Gensplash has the same kernel configuration requirements
|
|
as bootsplash, but works properly with any framebuffer device.
|
|
- To build a kernel with Genkernel you must have
|
|
"Block devices->Loopback device support"
|
|
"Block devices->RAM disk support"
|
|
- To boot genkernel properly, the kernel config must have
|
|
RAM disk support and Initial RAM disk support. You should
|
|
also set your "Default RAM disk size to 8192"
|
|
|
|
BOOTING A KERNEL WITH INITRD:
|
|
|
|
GRUB:
|
|
real_root= needs to point to your root partition
|
|
root= needs to point to the ramdisk (should stay at /dev/ram0)
|
|
init= needs to point to the linuxrc file to execute on the ramdisk
|
|
vga= should be the resolution you want your screen. 0x317 is
|
|
1024x768 - 16bpp and you'll get a pretty bootsplash if
|
|
configured properly
|
|
|
|
