Default value is "arch". This implies that all device mapper node
for snapshot devices will be for example: arch_root-image.
This helps AIF to hidden these devices from "Device Configuration".

* 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]

* Change from none -> union (looks like util-linux is confused BUG?)
Avoid the message: "umount aufs failed: not found" at shutdown.
#1 mount -t tmpfs none /something
#2 mount -t tmpfs xxxx /something
The output of findmnt -rnu -o SOURCE will be blank in #1.
* Change from aufs -> auto, make its more generic.
* Update devpts and shm entries.

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.

-D <install_dir> allow to select install directory on target media
defaults to "arch".
There is a new %INSTALL_DIR% macro for syslinux.cfg.
This is how ISO will look now:
/syslinux only syslinux related files (syslinux.cfg, *.c32, etc)
/arch/ isomounts + *.sqfs images
/arch/boot/ Linux + initramfs + Memtest86+ + other files for early boot stage

Newer nbd-server uses config file instead of parameters via cmd line (deprecated).
Also does not use a fixed port (oldstyle).

[archiso]
readonly = true
exportname = /tmp/archlinux.iso

When remastering the image onto a USB volume, you might want to reuse
an existing partition without filling the root with lots of archiso
files. The archisobasedir parameter allows to specify a new root
directory, isomounts and all images will be searched in this directory.
Otherwise archiso_pxe_nbd hook can configure the incorrect network card,
because ipconfig will configure all interfaces available.

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)

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

Some basic changes to make archiso hooks work with the next mkinitcpio 0.6
Tested under KVM, a ""2010.02"" and works fine with it.
NOTE: current mkinitcpio-0.5.99.2-2 does not include "losetup", maybe
will be included in next version, see #[1]. For now must be added manually.

Rename ramdisk_size parameter to tmpfs_size to avoid conflict with
the kernel parameter that is for old ramdisk based blockdevs (/dev/ramN)
and confusion to users.
The kernel parameter ramdisk_size=N is in "N * k size", while tmpfs
size=N is in "N * [ k | m | g ] byte size" or "in N% of RAM",
like is used by default on archiso.
This parameter is used only for tmpfs in size option.

fstype from klibc don't detect a vfat formatted blockdevice when try to
mount /dev/archiso to /bootmnt. Some users don't use the recommened
method with dd to bring the image to their USB stick. If they for ex.
use Unetbootin to put the iso image on their (v)fat formatted stick they
got lost with a kernel panic cause fstype won't detect vfat, so the
mount and the later squashfs bindings traps.
