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)

when no aufs branch is mounted, because mount type is bind.
Also, makes the code more clean :)

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.

As in title, this patch cleans up opt flags that exist for no reason and
adds additional flags to modify the disk meta info which would otherwise
be hardcoded.
I wasn't quite sure about the user directory part but it doesn't seem
like a good idea to put that part into the script and therefore I
commented it out. It would probably interfere with rc.local scripts that
take care of skel copying. I replaced the part after the TODO with a
safe guard to make sure that people who are not aware of the changes
will not be caught by surprise.

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.

The current implementation in how partition is created for ext2 img
it looks a bit bad.
This patch makes the partition in more standarized way, respecting
cylinder alignement:
* The size of resulting image will be in cylinder multiple ~8MB.
* Use fdisk instead of sfdisk (sfdisk write some bad information)
* Make the result image in one pass, instead of concatenating.
Also the advantage is that with this can add another partitions
without any issues in the usb-flash-drive with this .img.

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.
