Good idea in principle, but you have to delete the file in a few more
places:

  /var/run/blkid.tab
  /etc/blkid/blkid.tab
  /etc/blkid.tab       # older debian
  /dev/.blkid.tab      # newer debian

AND! ... you have to check that the file you're going to remove isn't
a symbolic link.  Because at least on some versions of debian,
/etc/blkid.tab is a symlink, and you *don't* want to remove it.

There is a g#is_symlink function for checking if a path is a symlink:
