* 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)

* ipconfig cmd writes a file in /tmp that is ready for direct evaluation.
We can use this instead of parsing the output, to do this some variable
renames are needed.

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)

* Support img_label=
* Allow use img_dev= as cow_device=
* Use new function _mnt_dev() from archiso.
* Check for error while setting loopback device.

This allow to take control again of these mountpoints outside initramfs.
(i.e: on deinitramfs stage at shutdown for unmount it)

Add some options to control where all COW files will be located.
Until this moment all files are located in a tmpfs filesystem.
Now is posible to set a device via a filesystem label or device node
plus a directory, where all these files will be stored.
All dm-snapshot devices will be persistent by default,
but this can be changed if wanted.
Take care, a filesystem that does not support sparse files maybe
is not the best choice for COW files, because they are created with
the same size (is apparent) like the read-only device (the image.fs inside .sfs).
Of course sooner or later, depending on use, these files actually end up
being as big as the read-only device.
KNOW-ISSUE: On shutdown in step "Unmounting Filesystems" will [FAIL],
all filesystem except $cow_device, will be unmounted/remounted-ro.
For this reason this change needs an archiso_shutdown hook, thats
unmount all block devices used by archiso. (Work in progress)

Separate this code from main mount hook, and make it more generic.
_mnt_dev(device, mountpoint, flags) ->
wait for device and mount, launch a shell if something goes wrong.

* 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.

Default (if not specified) -w work -o out.
-o <out_dir> is only used by 'iso' command.
Adjust build.sh of releng and baseline profile to reflect this change.

- work <- $work_dir
- out <- $out_dir

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

The name of the bootloader is syslinux, while isolinux is just one
of many components. isolinux.bin now also accepts syslinux.cfg
as a configuration file name (as do all other loaders).
Thus, rename the isolinux/ folder to syslinux/, and rename
isolinux.cfg to syslinux.cfg. The only occurrence of 'isolinux'
is now the actual loader file 'isolinux.bin'. This makes
the transition from isolinux to the other syslinux loaders
easier when remastering the ISO onto another medium.
