Without trying to be difficult, is oe-core really the place to support 
and spend effort ensuring NTFS/exFAT formatted drives are supported?

Could these improvements not stay in meta-oe? I don't really see support 
for essentially propriety filesystems as a core feature of a Linux build.

Shout up if I'm talking nonsense, just my 2p.
