fstab-sys will mount nonroot nfs as well, so we need to split the necessary
code from nfsroot to start rpc daemon as hook script.

ssh module will need root user in /etc/passwd, so add root and nobody
to /etc/passwd in 99base instead of nfs module

Like -H, we need to poll every module to check if it is needed
to mount a specific device in '--mount'.

While on some systems (like Fedora) rpc_pipefs is mounted
automatically when sunrpc module is loaded, on Debian based systems it
needs to be mounted manually.
/tmp/nfs.rpc_pipefs_path can contain the path where
/var/lib/nfs/rpc_pipefs will be moved before switch_root.
This is useful if /var is a separate partition in the real root.
--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
TODO: /etc/passwd and /etc/group are not removed yet due to 90mdraid.
dledford said he'll go in and clean this up since he has the hardware
to actually test the mdmon stuff.
it solves the following case:
root=/dev/nfs nfsroot=server:/path
- the server could be reachable on any interface
- any interface can get an IP by dhcp
- only one IP is allowed to mount the root
Udev rules set a /dev/root symlink to the real root and add
a mount script to /mount/. This enables the proper use of pre-mount
scripts and prevents mount being killed by a udev timeout.
