I checked my Autobuilder status, and it looks like I did checkout the
master branch instead of dylan. The config I used as an example was
nightly-arm.conf. Is there a better one to use as a starting point?

Good to know. Once I get my build working, I'll submit a patch with
updates to the README files once I figure out what I did wrong.

Ah, there it is. I see the auto.conf and it has the settings I expected.

I changed the line as suggested, restarted Autobuilder and forced a
rebuild. However, the new layers were not added to the bblayers.conf
file. Is there some other step I need to do to have these settings
take affect?

On my development machine I did a clone of poky, switched to the
dylan-9.0.1 tag and then applied the 10 patches. I wasn't sure if this
patch set was planned to be applied to dylan, so I've held off on doing
anything else.
So probably the best move would be for me to find a good place to have
a local git server for our development, clone poky and point to
git.yoctoproject.org as the upstream source, locally apply the patches
I want on the dylan branch and then tell Autobuilder to use our local
git for poky. Does that sound about right?

I'm setting up Autobuilder on a new machine that has no other toolchains
In place. I'm attempting to do the bare minimum steps per the
instructions to get the Autobuilder to work for our setup. So I'm
assuming that if I want to use qemu, I need get an SDK and tell
Autobuilder where the toolchain resides? How do I tell Autobuilder
where the toolchain is? I haven't seen that configuration item.
Speaking of qemu, I see in the instructions that it says if I want to
run sanity tests I need to get tight-vnc. I don't see tight-vnc in my
host system's package options (Ubuntu host) but I do see several other
vnc options (x11vnc is one of them). Does it have to be tight-vnc or
would another vnc server work?

If I understand what would be best to do for 4., I probably should setup
A git server for internal development anyway. In that case, moving our
layer to our git server would be the best move. But, I'll open up an
issue anyway, and you can decide if there's much call for expansion
of CheckOutLayers to other version control systems.
