From: "Yann E. MORIN" <yann.morin.1998 at free.fr>
The previous default, zero, just meant "use the default value of the
filesystem generator", which happened to be 5% (the traditional value
for all ext-creating tools we've ever seen).
So, change the new default accordingly to 5%.

+ The number of blocks on the filesystem (as a percentage of the
+ total number of blocks), that are reserved for use by root.
+ Traditionally, this has been 5%, and all ext-related tools still
+ default to reserving 5% when creating a new ext filesystem.
