650 x 1024 x 1024 is the actual limit that you can get on a 650MB CD,
give or take a few k, depending on padding. I generally decide that
an image is not releasable if it's bigger than 681,000,000 bytes, just
to be safe.
The art of getting somewhere near that is not very deterministic
though, and trying to get all the architectures to be somewhere near
it is a bit of a pain, which explains why only a couple of the
official CDs are larger than 645MB.
The contents of:
debian-cd/tools/boot/potato/boot-*.calc
are rather important in getting this to work.
For the recent potato run, I found that the sparc CD1_NONUS was too
big, so did this:
--- tools/boot/potato/boot-sparc.calc 2000/06/11 13:12:55 1.1
+++ tools/boot/potato/boot-sparc.calc 2001/11/19 07:41:42
@@ -1,4 +1,4 @@
-BOOT_SIZE_1=0
+BOOT_SIZE_1=10
BOOT_SIZE_2=0
=-=-=-=-
which is probably a little excessive, but does the trick.
Cheers, Phil.
