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.

Please look at my comment about a possible alternative way of doing
it, in a more generic one.
