* 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.
Original idea from Baurzhan Muftakhidinov.

-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).
Sample nbd-server.conf that works with this change:
-- CUT HERE --
[generic]
[archiso]
readonly = true
exportname = /tmp/archlinux.iso
-- CUT HERE --

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.
* 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=

Currently works partially since in bash "*" is not expanded.
Old dirs removed, always empty dirs removed from list.
Also cleanup sync databases from pacman 3.4.0, avoiding problems with
pacman -Sy since "sync" directory is deleted.

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.
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.
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
