Because /dev/vg/vol is just a symlink to /dev/mapper/vg-vol, and mount
dereferences it and uses the authoritative name when it actually mounts it.

It can be rather confusing to have an fstab full of /dev/vg/foo but then see
/dev/mapper/vg-foo listed by mount, it does tend to make one think they
should just use /dev/mapper paths directly.
