> Running `mount -fv /mnt/pnt` incorrectly updates /etc/mtab

This one is bogus.

Manpage:

=====
-f     Causes  everything  to  be  done  except  for  the  actual  system call;
       if it's not obvious, this ``fakes'' mounting the file system.  This option
       is useful in conjunction with the -v flag to determine what the mount
       command is trying to do. It can also be used to add entries for devices that
       were mounted earlier with the -n option.
=====

Also, we need it in /etc/init.d/checkroot to regen /etc/mtab ...
