Thanks for the correction.  FAT32 is indeed about as universal/tolerable of
a standard as possible in 2015.  But might not be wise on large SD cards
going forward, given 32GB is the traditional Windows limit for FAT32
partitions.  And of course FAT32's a bit slower than modern filesystems,
and worse 4GB content zip/repos (FAT32's upper limit) will appear before we
know it?

On balance, SD Card industry standard exFAT seems (to me) more future-proof
for a hassle-free "grassroots content" partition over coming years, for 1%
of the SD card of whatev.  Or perhaps NTFS ~if~ file owners/permissions are
more important than Mac support.

In the OLPC ecosystem, only Open Firmware has an 8.3 limit, and there's
