If you don't mind, I'd like to just post this feedback from our
conversation.â I didn't realize I had skipped the mailing list! Thank you!

James Stortz:
Do you know if there's a way to do this and still keep the rw layer on the
root fs itself?
Essentially, the layers cannot have the parent-child relationship on the
single fs. By using a loopback-mounted fs image file, you can. I guess
you will need to apply aufsN-loopback.patch.
# just to show the scenario (didn't test actually)
file=/rw-layper-image.ext2
truncate xxxMB $file
mkfs -t ext2 $file
mount -o loop $file /rw
mount -t aufs -o br:/rw:/ none /

James Stortz:
Or better yet, maybe there could be an exclude option or something of
the
like. That would be really nice. Maybe I can write a patch. I just don't
have the time right now to get into it I think.
Exclude?
I am not sure what you mean, but generally you can exclude something
by bind-mount.
# mount -t aufs -o br:/rw:/ro none /aufs
# mount -o bind /ro/dirA /aufs/dirA
# mount -o bind /rw/dirB /aufs/dirB
# mount -o bind /ro/fileA /aufs/fileA
    :::
All these dirA, dirB and fileA are provided directly from /ro and /rw.
Aufs doesn't provide them to users.

Hello James,
James Stortz:
What is a standard method for mounting a rw layer over the top of my
root
fs?
I'd suggest you check these as a first step.
- samples in aufs-util.git as well as the old aufs1 CVS tree on
 SourceForget.
- LiveCDs, SLAX, Knoppix and other distributinos.
