I might also suggest an init job to unmount all fusefs file systems at
shutdown. It appears that the fuse daemon may exist before volumes are
unmounted. I was having to do a disk repair fairly often to fix issues with
both NTFS and ExFAT volumes after updating them and shutting down the
system with them still mounted.
I added the following init script to /usr/local/etc/rc.d. Since then, I
have not had a corruption of an NTFS system. I am not currently using ExFAT.
# PROVIDE: unmount-fuse
# REQUIRE: DAEMON
# BEFORE: LOGIN
# KEYWORD: shutdown nostart
local err fusefs
# unmount fuse filesystems
echo -n 'Unmounting all fusefs filesystems...'
for fs in `df | grep ^/dev/fuse | cut -f6 -w` ; do
echo -n " $fs"
