--kernel-only
only install kernel drivers and firmware files
--no-kernel
do not install kernel drivers and firmware files
All kernel module related install commands moved from "install"
to "installkernel".
For "--kernel-only" all installkernel scripts of the specified
modules are used, regardless of any checks, so that all modules
which might be needed by any dracut generic image are in.
The basic idea is to create two images. One image with the kernel
modules and one without. So if the kernel changes, you only have
to replace one image.
Grub and the kernel can handle multiple images, so grub entry can
look like this:
title Fedora (2.6.29.5-191.fc11.i586)
root (hd0,0)
kernel /vmlinuz-2.6.29.5-191.fc11.i586 ro rhgb quiet
initrd /initrd-20090722.img
initrd /initrd-kernel-2.6.29.5-191.fc11.i586.img
initrd /initrd-config.img
initrd-20090722.img
the image provided by the initrd rpm
one old backup version is kept like with the kernel
initrd-kernel-2.6.29.5-191.fc11.i586.img
the image provided by the kernel rpm
initrd-config.img
optional image with local configuration files
This introduces detailed cmdline parsing, warning or aborting if the
cmdline does not contain arguments according to the spec.
Makeing sure the parsers don't just call getarg for netroot et al,
allows their reuse inside netroot to analyse dhcp root-path as well.
Hence we can get rid of the current netroot hooks. The hook itself stays
in order to add further modules which should run before netroot handlers
are called.
This has one drawback: nfsroot needs some more logic to handle nfs
specific data inside dhcp root-path.
The parsers have been writting according to current discussions about
cmdline arguments. This lead to the "discovery" that some test-cases
violate the spec. These tests have not been removed, but change to
"must fail".
