VFAT is lacking many features of real file system. VFAT is used
on MMC/SD cards by default for PC i.e. Windows/OSX/etc compatibility
reasons.

You need to use some other file system (it's a bit complicated,
is there a Wiki page on using other file systems on the MMC/SD
cards?).

Dpkg must remove aborted installations, otherwise you would soon
run out of disk space on rootfs even for root (and as a result device
would be in reboot loop if you'd reboot it at that state).
