85d243ff58 [archiso] Use dm-snapshot instead of aufs2 (A.K.A. "The Big Commit")
* Use device mapper + snapshot module, instead union layer filesystem.
  * A block-level approach vs vfs-level.
  * No more unofficial (Linux) things.
  * More memory is needed.
* Refactor mkarchiso.
* Refactor hooks/archiso.
* Fix install/archiso_pxe_nbd
  (due recent change in mkinitcpio-0.6.15 on checked_modules()/all_modules())
  [Thanks Dave for the improved workaround]
* New configs/releng to build official images.
  * Works with a Bash script instead of Makefile.
    (better control and easy to maintain)
* Remove configs/syslinux-iso.
* Remove archiso2dual script. Integrate functionality in configs/releng.
* New configs/baseline to build the most basic live medium or use as template.
* New README (draft). [Thanks Dieter for fixing english grammar]

06a8c66eae [archiso] Add support to mount iso in loopback mode.
Add two parameters:

img_dev=/dev/sdNM
   where /dev/sdNM is the device where .iso is located.
img_loop=/path/to/arch.iso
   where /path/to/arch.iso is the full path of the .iso in the device img_dev.

Original idea from Baurzhan Muftakhidinov.

1bbeeb0e5b Rename directories and parameteres to be more descriptive
* squashfs images that will be part of read-only branchs for union mount in /
  are mounted on /ro_branch/{image_name} instead of /tmpfs/mnt/{image_name}
  (and avoid empty dirs on live env under /mnt)
* tmpfs that will be part of read-write branch for union mount in /
  is mounted on /rw_branch instead of /tmpfs
* tmpfs that is for store *.sqfs images when copytoram=y, is mounted on
  /copytoram instead of /tmpfs.sqfs

* tmpfs_size= parameter renamed to rw_branch_size=
* tmpfs_sqfs_size= parameter renamed to copytoram_size=

f0aba9b876 Make it compatible with latest mkinitcpio.
Latest init script mounts a /dev FS, so /dev/loop0 will disappear.
Create loop0 on /lib/udev/devices so udev copy to /dev on startup.

aeaec35905 archiso_pxe_nbd: Remove unnecessary/unsupported network modules
The archiso_pxe_nbd hook adds all network modules, including ones that
are not supported: The hook only supports ethernet devices, so there
is no need to add wireless, wimax, ppp, irda and plip modules.

Adding the wireless modules had an undesired side effect: The
wireless driver was loaded in the initramfs stage, where the
required crypto modules were unavailable. This caused the
initialization of the wireless devices to fail.

This patch removes all network modules except ethernet.

830555f71a [archiso] Add nbd hook, to make posible boot archiso from PXE via a NBD.
nbd (network block device utilities) package is required. This package is in AUR
at this moment: http://aur.archlinux.org/packages.php?ID=9691
Also mkinitcpio-nfs-utils is required for ipconfig.

fc9a01e713 Remove archiso_early hook, use /dev/disk/by-label/${archisolabel} instead.
Takes the advantage of already symlinks created on /dev/disk/by-label/ by
60-persistent-storage.rules add by udev hook.

Tested on:
* Real machine as CD-ROM and USB key drive.
* KVM as CD-ROM and DISK (for both modes, in combination with IDE and SCSI)
* VirtualBox as IDE CD-ROM.

IMPORTANT note: Since isohybrid is a hack, if more partitions are added to
USB key drive, filesystem on these partitions MUST have LABEL, otherwise
USB key will fail to boot. Anyway there is an option archisodevice=,
to force and specific device where live-media reside.
(Maybe isohybrid will change the hack method used in a future)

c65f463ce3 Welcome back copytoram= option
Fixes FS#17182: copytoram=y does not work with aufs

The solution is simple, just use a directory outside aufs tree.

* If copytoram=y, then another tmpfs is mounted but on /tmpfs.sqfs
* Add a new option: tmpfs_sqfs_size= (default to 75%)
* Lock cdrom drive is not locked if copytoram=y

7d7dad06e2 Take advantage of module autoloading when mounting images as loop
* Make first /dev/loop0 device at archiso install hook.
* Remove unneeded losetup, all is done directly via mount.
* Images are now mounted on /tmpfs/mnt/image-name instead of
/tmpfs/mnt/loopN, removing unneeded counter.
* Add some variables to make code more readable.

b880be1ae9 Implement mount hook function in archiso hook.
Next version of mkinitcpio > 0.6.2 implements mount hook functionality.
So can avoid skipping normal flow of main init script, and removing common
end code with it.

8a37489379 Advanced USB delay handling
USB boot delay is now handled with the usbdelay kernel param (default=0)

We use the built in delay of usb-storage to control this. by setting the
module's delay param. If your USB device doesn't work on first boot, try
setting usbdelay=10 or so
