* In that way, we have unified directory scheme among {pxe,sys,ext,iso}linux,
  sharing the same directory structure and config files.
* Also enable IPAPPEND (will show a warning message about unknown directive in non-pxelinux before menu)

NEW:
* Rename syslinux*.cfg -> archiso*.cfg
* Now syslinux.cfg is only a "loadconfig" trick like we are doing for isolinux
* All paths are now relative to %INSTALL_DIR% ($archisobasedir) (Default: /arch/)

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)

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)
