sarge/powerpc - Kernel install failure

[Allen Unueco <allen@premierweb.com>]

I failed to install Sarge from the latest (20040516) official testing CD.

After base-config while trying to --configure the kernel-image package I 
see the following error:

Internal Error: (=D) is not a directory!

Then dpkg fails

I poked around a bit and found this on line 99 of 
kernel-image-2.4.25-powerpc-smp-prep.postinst

----
...
my $image_dir         = "=D";        # where the image is located
...
die "Internal Error: ($image_dir) is not a directory!\n"
    unless -d $image_dir;
...
----

I don't really know how the postinst script works so I was just playing 
and changed "=D" to be "/boot" and at that point I could --configure the 
kernel-image package successfully.
