The default amount of reserved space for ext2/3 is 5% - this amounts to
about 2GB of a 40GB filesystem that the builder user can't make use of.
We don't need this much reserved so peg it back to 0.5% which should be
more than enough.

Hi Paul,
This reminds me of something slightly similar:
Can we enable the -z option of genext2fs in IMAGE_CMD_ext3()?
For a 40G image, this would save the building host many giga bytes, and make the conversion "from .ext3 to .hdddirect" faster.

Thanks,
-- Dexuan

In principle if it works then we should be able to do it, but I have no idea 
if there are any other side-effects of using -z.

Cheers,
Paul
