mtab not holding changes after reboot

[Slicer]

I am using the Hot To How To Set Up Software RAID1 On A Running LVM System (Incl. GRUB Configuration) (Debian Lenny) on my EBox 1.4 install. (This is using Ubuntu 8.0.4.4)

The problem is when I edit the /etc/mtab/ under section 4 Creating Our RAID Arrays it does not hold the change on reboot.

Has anyone seen this?

Here is the section from the HowTo----

Next replace /dev/sda1 with /dev/md0 in /etc/mtab:

vi /etc/mtab

/dev/mapper/debian-root / ext3 rw,errors=remount-ro 0 0
tmpfs /lib/init/rw tmpfs rw,nosuid,mode=0755 0 0
proc /proc proc rw,noexec,nosuid,nodev 0 0
sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0
udev /dev tmpfs rw,mode=0755 0 0
tmpfs /dev/shm tmpfs rw,nosuid,nodev 0 0
devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=620 0 0
/dev/md0 /boot ext3 rw 0 0
---------------------------------------------------------------

here is what my file looks like after a reboot..


/dev/mapper/hercules-root / ext3 rw,relatime,errors=remount-ro,usrquota,grpquota 0 0
proc /proc proc rw,noexec,nosuid,nodev 0 0
/sys /sys sysfs rw,noexec,nosuid,nodev 0 0
varrun /var/run tmpfs rw,noexec,nosuid,nodev,mode=0755 0 0
varlock /var/lock tmpfs rw,noexec,nosuid,nodev,mode=1777 0 0
udev /dev tmpfs rw,mode=0755 0 0
devshm /dev/shm tmpfs rw 0 0
devpts /dev/pts devpts rw,gid=5,mode=620 0 0
/dev/sda1 /boot ext3 rw,relatime 0 0

------------------------------------------------------------


not sure how to get the mtab file to hold the needed change.

What's the output of

mount

after the reboot?
