NetInstall 10.5.7 installing to /var/run/DoNotInstall

Question

Hello, has anyone tried creating a 10.5.7 slipstreamed NetInstall? I've found that while 10.5.6 deploys fine, 10.5.7 doesn't. The logs show many files trying to install to /var/run/DoNotInstall. Consequently, the installation fails due to "no space left on device". I have tried the following combinations with a retail Leopard DVD image:
10.5 base + 10.5.6 Combo Update (succeeds)
10.5 base + 10.5.7 Combo Update (fails)
10.5 base + 10.5.6 Combo Update + 10.5.7 Update (fails)
The SHA1 hash of the 10.5.7 Combo update is correct, and I have logs from both failed installs if anyone would like to see them.
Thanks in advance,
X

@xorlogic and @iSauce: I, too, would like to know what you have found.
I have tried posting my findings and logs to the "OS X Server", "Installers" and "Imaging" Apple lists with no useful information.
I have tried using 10.0, 10.4, and 10.6 as the bases. I can use any update up to and including 10.5.6 without a problem, but I seemingly run out of space with 10.5.7 around "Activity Monitor" or "Address Book" depending on variables I have not yet determined.
A thought I had but don't have the skills to test is this: Can we use a payload-less package that uses a pre-flight script to link this mysterious "/var/run/DoNotInstall" to "/dev/null" instead?
In the next day or two, I hope to attempt starting with a 10.5.0 base and adding each of the delta updates one at a time up to 10.5.7 and seeing what that does.
I have this thread's RSS in my bookmarks bar which is how I found @iSauce's reply so quickly. I will be watching with bated breath for that happy little '(1)' to appear.
