Amadeusz Żołnowski 6bde7a17be suppress modprobe errors on builtins (credits to Kay Sievers)
Install /lib/modules/$kv/modules.builtin.bin to suppress modprobe error
messages saying module was not found, while it's built-in.

Credits go to Kay Sievers who enlighten us about meaning of this cool
file.

Amadeusz Żołnowski 4bacdf2811 99base/init: honor env. vars provided by kernel (PATH, HOME and TERM)
Let take a look at Linux sources, /usr/src/linux-2.6.35/init/main.c:

  204: char * envp_init[MAX_INIT_ENVS+2] = { "HOME=/", "TERM=linux", NULL, };

  857: run_init_process("/sbin/init");

  817: static void run_init_process(char *init_filename)
  818: {
  819:        argv_init[0] = init_filename;
  820:        kernel_execve(init_filename, argv_init, envp_init);
  821: }

As we can see HOME=/ and TERM=linux are provided for init and this might be
expected on some systems (Gentoo comes to my mind, here ;-)).  That's why we
should give to init the same set of env. vars as Linux kernel does.

Ian Dall ecefdfc280 95fstab-sys: mount all /etc/fstab.sys volumes before switch_root
A new dracut module to implement fstab.sys handling

This module implements fstab.sys handling. This has to happen after the root
mount and before the nfsroot-cleanup pre-pivot at least. I've made to happen at
the beginning of the pre-pivot scripts, although it should maybe be at the end
of the mount scripts. This latter would be harder to do because the actual
mount is currently done by 99mount-root.sh and there is no 2 digit integer
higher than 99 :-(

There are perhaps other ways of achieving this end, such as having the
nfsroot-cleanup trawl through the newroot's /etc/fstab and auto-magically
figure out if there are any mounts which are pre-requisites for the
/var/lib/nfs/rpc_pipefs mount and do them first. Likewise post pivot,
/etc/rc.sysinit could figure out of there are any pre-requisite mounts for
/var/lib/stateless/{writeable,state} before doing those mounts. In short, make
it the responsibility of anything doing a mount to check if there are any
pre-requisites in /etc/fstab and mount them first. However, this spreads the
changes needed over more places, so I favour the fstab.sys approach. Also, who
knows what other uses administartors may have put fstab.sys to? and this undoes
a regression caused by the move from mkinitrd to dracut.

James Laska b2dff45423 lvm: support for dynamic LVM SNAPSHOT root volume
I'm looking for a way to have a system with disposable storage that can be
rebooted and all filesystem changes are thrown away.  After reboot, the system
starts with a fresh root volume again.  The use case is for automated testing.
We run test scripts that could potentially not clean up after themselves.

This is almost like stateless, but the storage is local to the system (not
iSCSI, NFS or NBB).

1. Install Fedora 13 using default partition layout
  NOTE: modify the layout to leave extra room in the LVM volume group
2. Apply attached patch
3. Update grub.conf to enable dracut LVM snapshot support.  Add the following
boot arguments

 rd_LVM_SNAPSHOT=vg_test1055/lv_snap (note the VG name will depend on your
system).
 rd_LVM_SNAPSIZE= (optional, defaults to size of volume specified with by
rd_LVM_SNAPSHOT)

4. Adjust grub.conf and fstab to use LVM snapshot
 $ sed -i -e 's|lv_root|lv_snap|' /boot/grub/grub.conf
 $ sed -i -e 's|lv_root|lv_snap|' /etc/fstab
5. Reboot system

Expected results (no value provided for rd_LVM_SNAPSIZE):

  dracut: Starting plymouth daemon
  dracut: rd_NO_DM: removing DM RAID activation
  dracut: rd_NO_MD: removing MD RAID activation
  dracut: Removing existing LVM snapshot vg_test1055/lv_snap

Matt Smith 7254c24a76 Merged cryptroot-ask.sh from plymouth to crypt module.
First, it's duplicate code.

Second, it did not allow those who had plymouth installed to use other
methods, like the new usb key file. When building the initram,
it would install the plymouth cryptroot-ask script, and not
the crypt module one.

Added these new items to crypt module's cryptroot-ask.sh:
  - 'unset' for used variables
  - udevsettle

The non-plymouth cryptsetup prompt was using $1 instead of $device.
Changed prompt number from 1 to 5, as this is much nicer.
I believe plymouth already does infinite prompts.

Also added unset for usb key. Just saw it didn't unset its vars.
