what is happening is that mount is failing because the fstab entry
is saying that the filesystem is ext3, but since the ext3 mount is
failing, the root filesystem is never mounted, which makes the
pivotroot operation fail, and that's why you're getting the "no init
found" error message.

One of way of making things more robust is to use an /etc/fstab entry
which looks like this:

/dev/hda1 / ext3,ext2 defaults 1 1

This will cause mount and fsck to first try ext3, and then ext2, so
that in the case where the filesystem is converted back to ext2 due to
a filesystem error, the system will actually come back up cleanly.
The only gotcha here is that the code to support having a list of
filesystems in /etc/fstab is relatively new, and I don't know what
version of Red Hat youre running; if it's too old, it might not have a
sufficiently new enough version of mount and fsck (in the util-linux
and e2fsprogs packages, respectively).

Another way of solving the problem would be to add something like the
following to the Red Hat's initrd linuxrc, before it tries to mount
the real root partition:

ext3root=`awk '{ if (($2 == "/") && ($3 == "ext3")) {print $1;}}' /etc/fstab`
if test -n "$ext3root" ; then
tune2fs --j $ext3root > /dev/null
fi

I think the problem is that the kernel doesn't have the ext3 driver compiled in. Do it and it should work.

If you have your /boot section on a seperate partition, then you could mount it as ext2 even though it may be formatted as ext3... they're basically the same fs.
