update:

I've been working on adding support for loopback files, porting GNU parted etc
lately, but I didn't have time to test it yet (I have to make a complete backup first...)
I have uploaded modified version of ke-recv and upstart (system-services) with some changes:
* only generate fstab if it is missing or requested using /etc/fstab.regen
* run optional /etc/init.d/pre-mount-once once before mounting
* support for mounting loopback devices (options in /etc/default/mount-opts)

feel free to test them at your own risk (backup first!) and you're welcome to help me.
parted still crashes on start. I have no idea why.


My plan is to run a script which performs repartitioning (incl. shrinking of ext3)
before mounting any partitions on the eMMC. If you just want to grow ext3 you can do it online using resize2fs.
I still need to work out a good solution for managing which partitions or files are exported per USB
and mounted as MyDocs or other directories.
