Nope. It does not preserve the selinux ACLs.

Oh! You DO have something there! Yes, I was pointing to the wrong
root label - that's for sure. But fixing THIS did not solve the issue.
Read on!

Yes, I added selinux=0 single to the line, booted, and whoa! In doing this
there was an extra HINT there! It says that the reason that it failed
to mount /dev/root was because it was expecting EXT3. This message was
not hinted in the normal boot up. So, I rebooted in knoppix and ran
qtparted and lo' and behold! My partition was formatted with ext2
filesystem type. Shoot! That did it. The problem I had was I did not
pay attention to the filesystem type when I formatted. Royal BF!

I KNOW that having a mislabeled swap mislabeled as seen by initrd does not
cause the process to stop, it just complains. I have done this many time
and used mkinitrd - and it works. Not a big deal here.
In case you were wondering:
+ cd /boot; mkdir backup; mv <kernel-version>.img backup/
+ mkinitrd <kernel-version>.img <kernel-version>
Done.

At the time I tried it but gave up, it was because I later discovered
that the partitons were formated as ext2.

Yup, or use mkinitrd to make a new one (see above) or simply relable
the drive to the one where the 'complaint' appeared ob boot up and
update your /etc/fstab to match.

Yup, it does. But does not really matter because copying anything
in these directories are 'erased' anyway, I hope.
Ok, in summary:
===============
1) Boot up Knoppix (although maybe LiveCD would do the same)
2) With both drive installed, click on the original / and /boot
drive partition icons on your desktop (like hda1 (/boot) and
hda2(/), for example) and these drives will be mounted RO in
/media/{hda1,hda2}.
3) Open a terminal window, and become root user (su)
4) Use Qtparted to create your new drive's partitions,
the /boot, /, and swap space. Pay attention to the fact
that your /boot and / should be ext3 filesystem type.
Make sure that you create the labels for each partition
and when completed out of qtparted, check with e2label.
4) Mount your new drive's / and /boot partitions to
/media/{hdb1,hdb2}
5) cd, into each directory then cp -a the source files into
each target directory:
a) cd /media/hdb1; cp -a /media/hda1/. . (for /boot)
b) cd /media/hdb2; cp -a /media/hda2/. . (for /)
6) Check the target /boot and / drive labels and relabel
if not correct:
a) check: e2label /dev/hdb1, relabel: e2label /dev/hdb1 /boot1
b) check: e2label /dev/hdb1, relabel: e2label /dev/hdb2 /root1
7) Edit the target /boot directory's grub.conf file
and update the root=LABEL=/root1 for each kernel
version if there is more than one.
8) Edit the target / directory's /etc/fstab file
and update the mount LABEL= for / and /boot:
LABEL=/root1 / ext3 defaults 1 1
LABEL=/boot1 /boot ext3 defaults 1 2
LABEL=swap1 swap swap defaults 0 0
9) shutdown system
10) Replace the original HD with the new HD
11) If grub fails, MBR is probably not placed on the
new drive. In this case, use rescue CD, check that
your intended drive is the correct one, then apply
grub-install /dev/sdX where X=letter of your new drive.
12) If on booting up on your new drive that you get a message
"Unable to access resume device (LABEL=*********)", this will
not stop your boot up, nor disable swap - just let it continue.
To fix this to your new swap label in /etc/fstab, log into
your system, become root user and:
a) cd /boot; mkdir backup; mv <kernel-version>.img backup
b) mkinitrd <kernel-version>.img <kernel-version>
c) You can reboot to check but this is optional.
I think that covers it.
Thanks to all who responded and aided me through the process
of discovery. It was hell, but worth it. I won't make the
same mistake twice... well, we will see. :P
