VERY EXPERIMENTAL
|
|
seems to work so far on amd64 and x86
|
|
|
|
DEPENDANCIES:
|
|
- bootsplash
|
|
- gcc/binutils
|
|
- bash
|
|
|
|
INSTALLATION:
|
|
|
|
put genkernel.conf in /etc
|
|
|
|
put genkernel executable in /usr/bin
|
|
|
|
put the rest of the files and directories in /usr/share/genkernel
|
|
|
|
|
|
|
|
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, this is all the arch-specific stuff, as well
|
|
as a generic kernel-config
|
|
|
|
|
|
IMPORTANT KERNEL NOTES:
|
|
- You MUST have devfs turned on at this time, but you MUST NOT
|
|
have "Automatically mount at boot" option turned on.
|
|
- 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"
|
|
- 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 at 0x317 indicates
|
|
1024x768 - 16bpp and you'll get a pretty bootsplash if configured properly
|
|
|
|
|
|
