Hello again:

Yes, it has been a while.  I was forced to set this project aside and 
just last night I had time to revisit it again.  Well, you all know how 
it is...

Ok, here is what I have in my fstab now:

###############################################################
/dev/sda1       /boot            ext2            noatime

Now, the machine attempts to boot but I get the following:

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

The thing is that as you can see on the fstab, the file system type on 
/dev/md0 is ext3 and not ext2.  Would any one be so kind to give me an 
indication of what is going on here?


Thanks,
