The required fix for dosfstools to work has been merged on OE-Core and
this allows this changes to be tested and merged now.
The following changes since commit 018824ece4a04245b4277d5c8afcccfd6ca75df0:
matrix-tui.inc: drop 'PRIORITY = "optional"' as it is the default (2011-12-14 01:05:59 +0000)

Allow generation by regular users without fancy setup requirements and
use of loopback and mount/unmount. Besides, this also includes
following improvements:
* use of megabytes when specifying SDIMG_SIZE
* remove restriction of filesystem to rootfs
Images that use this class needs to generate the rootfs filesystem and
set ROOTFS variable according.

Sorry for the top-post. Using the number of clusters is important to make sure that the DOS partitioning is valid. I'm not confident that we'll end up with a whole number of clusters using this method. Perhaps it isn't completely critical, but I'm not 100% comfortable getting rid of it.

You can now try it :)

The 'oldmethod' is built using the old method, the other one with otavios patches.

This should probably switch to using mcopy + dosfsck like the OE core patches Darren posted

Do you know if fsck will work on the loop devices properly? At least ext4 needs an fsck pass to add dirhashes.

Isn't the question whether the ROM bootloader handles it or not? If so
we need to test on Beagleboard classic (Rev B & Rev C) and -xM as well.
The classic's on board flash should be wiped for a real test.

I am converting those to use mtools and avoid the dosfstools -d usage.
Please hold the merging until I do that.

* [PATCH v3 1/3] sdcard_image: rewrote to avoid using loopback and mount/unmount

Allow generation by regular users without fancy setup requirements and
use of loopback and mount/unmount. Besides, this also includes
following improvements:
* use of megabytes when specifying SDIMG_SIZE
* remove restriction of filesystem to rootfs
Images that use this class needs to generate the rootfs filesystem and
set ROOTFS variable according.
