What do the 2 zerros at the end of the line mean and why is the

dump and pass. The fstab man page will explain it

fs_freq and fs_passno

See man 5 fstab

Though '/' should be '0 1'. fs_freq is all but obsolete

       The fifth field, (fs_freq), is used for these filesystems by the
dump(8) command to determine
       which filesystems need to be dumped.  If the fifth field is not
present, a value of  zero  is
       returned and dump will assume that the filesystem does not need
to be dumped.

       The  sixth field, (fs_passno), is used by the fsck(8) program to
determine the order in which
       filesystem checks are done at reboot time.  The root filesystem
should be  specified  with  a
       fs_passno  of  1,  and  other filesystems should have a fs_passno
of 2.  Filesystems within a
       drive will be checked sequentially, but filesystems on different
drives will  be  checked  at
       the  same  time  to utilize parallelism available in the
hardware.  If the sixth field is not
       present or zero, a value of zero is returned and fsck will assume
that  the  filesystem  does
       not need to be checked.

Not to be pedantic, but it's '0 1' for the / partition  :-)

Others have referred you to the man pages that describe these 
settings, but what isn't obvious is that these are for ext2/3 
filesystems only. Field 5 is used by dump/restore which only 
works on ext2/3.

If you use reiserfs, these fields must be '0 0' as reiser can do 
the right thing at mount time by itself.
The same goes for all other filesystems (cdroms, tmpfs, udev, 
etc etc)
