Yeah. I just remembered. My mistake for my earlier mails claiming
otherwise. VFAT doesn't have the concept of permissions, unlike the
others :-)

Really weird.

The original bug reporter had the timestamp of his mounted VFAT
filesystem thrown back to December 31 1969. At least I'm better off than
him (mine was just Jan 1 1970 :-)

This is actually an outstanding bug in Debian Sid's "mount" package.(bug
#171309, reported with util-linux source 2.11x) Workarounds include not
mounting a VFAT filesystem or downgrading the mount package . Anyway, I
downgraded the mount package to its version in stable (2.11n) and the
problem's gone.
