I noticed that rebooting with devices mounted can result in:
1) Leaving directories in /mnt/ when not using autofs
2) Leaving symlinks in /mnt/ when using autofs

They can cause mounting errors on further attempts.

With mountd this problem didn't exist due to using /tmp/mounts/ instead
of /mnt/. With block(d) we have to find some solution.

This patches takes care of removing files that can cause mounting or
symlink-ing errors. Worth implementing may be also a /mnt/ cleanup done
at boot/init time.

Rafał Miłecki (2):
  block: remove mount target file if it's a link
  blockd: remove symlink linkpath file if it's a dir or link
