New losetup from util-linux 2.21 uses new /dev/loop-control from Linux 3.1.
Needs mkinitcpio-0.8.2+ (provides modules.devname, or workaround with earlymodules=loop)
Get advantages from it! Removing custom shell code.

On machines with common graphics chipsets (radeon, intel, nvidia), enable
KMS early. Downloading images from a remote server can take time, better
view the status with a nice resolution.

Otherwise does not work.

Looks like my test was made before introducing symlinks
and using directly libnss_dns-$VERSION.so.2 as libnss_dns.so.2.

Do not "add_binary /lib/libnss_dns.so.2", because will add libnss_dns-VERSION.so.2 as libnss_dns.so.2
Is not an issue will work (nobody links directly to VERSION), but is not nice.

Its add support for downloading the ISO image via HTTP/FTP with curl or download *.sfs files.
The files are downloaded on /run/archiso/curlspace (tmpfs) and setup a loop dev from it
(like in archiso_loop_mnt) in the ISO case, or just do a bind mount to
/run/archiso/bootmnt in the other case.
This hook must be located after archiso_pxe_nbd in mkinitcpio.conf, in that way
NBD is the default.
New bootparm:
* archiso_curl_url=(first form)
archiso_curl_url=http://192.168.0.7/archlinux/iso/archlinux.iso (absolute form)
Use an absolute URL. Fetch the entire ISO
archiso_curl_url=ftp://${pxeserver}/archlinux/iso/archlinux.iso (relative form)
Use the as IP the same server where PXE reside. Fetch the entire ISO
* archiso_curl_url=(second form)
archiso_curl_url=http://192.168.0.7/archlinux/iso/unpacked (absolute form)
Use an absolute URL. Where unpacked (an example name) is a directory where
${archisobasedir} ("arch" by default) is located with all *.sfs.
This fetch only needed files.
archiso_curl_url=ftp://${pxeserver}/archlinux/iso/unpacked (relative form)
Use the as IP the same server where PXE reside. Where unpacked (an example name)
is a directory where ${archisobasedir} ("arch" by default)
is located with all *.sfs. This fetch only needed files.
* curlspace_size= Set a size for a tmpfs filesystem where files are downloaded.

One hook only setup the network device (archiso_pxe_common) the other
setup the NBD client (archiso_pxe_nbd).
New bootparam:
archiso_pxe_srv=IP
Allow to set an IP different from the PXE server.

* Now bootmnt/img_dev is always a ro-mount,
and cowspace is first ro-mount then rw-mount.
* Fix a "hidden" bug: at the time of test [[ -ef ]], if devices nodes
are not ready, such test will fail then archisodevice will mounted ro and
when cow_device is mounted to be rw it fails.
(I recently suffered this on a machine with slow USB)

STATUS: Working (std boot, loop_mnt, pxe) with copytoram=[y|n].
NEEDS: initscript > 2011.07.3, mkinitcpio > 0.7.2, mkinitcpio-busybox > 1.18.5-1
Purpose: we need this for propertly unmount $cow_device,
used for persistent dm-snapshot devices.
This hook is based on work from Tom Gundersen[#1],
but adapted for archiso things (specially the shutdown script)

* These files was added during developement stage of dm-snapshot branch
of archiso. Never was used, sinse archiso works directly with dmsetup
and with device nodes in /dev/mapper/
* Added 11-dm-initramfs.rules to keep dm info about nodes persistent
in udev db across initramfs/real-root.

* 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]

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.

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.

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

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
