Mounting local filesystem failed on boot

[Muhammad Yousuf Khan <sirtcp@gmail.com>]

i am getting Mounting local filesystem failed on every boot. and the
problem line in fstab is "proc            /proc           proc
defaults        0       0"

here is my fstab

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# / was on /dev/sda3 during installation

# /boot was on /dev/sda1 during installation
UUID=52f78bea-8afd-4bee-a3b9-2498abceb55f /boot           ext3
defaults        0       2
# swap was on /dev/sda5 during installation
UUID=6baabb6e-ab2d-4bfc-a21a-05ee8a0af001 none            swap    sw
           0       0
#/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto     0       0


the problem line is proc mounting. when i comment this line error disappear..
i haven’t created proc partition during installation. i just created 3
 partitions boot, swap and root
However the error is gone by commenting the line but i am worried how
it going to impact my system
and what this proc mount is for. as i haven’t created it.

Thanks,
