Detect duplicates in the extra images used for installation
Several files included under install.{386,amd} are actually identical to
others. Rather than duplicating them attempt to detect this and hardlink
them.
Since images can be downloaded from the web at build time it is not
always possible to detect identical files by looking for the symlinks
created by the debian-installer build. Instead we pass a list of
potential "doppelgangers" to extra_image each of which is checked for
similarity to the new image.
I added gtk/vmlinuz (which is always the same as plain vmlinuz) which
although not necessary makes it more explicit which kernel goes with the
initrd at very little cost.
Hardlinks are used in preference to symlinks since these are expected to
work better with isolinux and the Xen tools.
didn't gave any result. This is useful when using partial mirrors built by
simple-cdd while trying to build a Debian CD using a newer d-i (in my case
etch CD with lenny d-i).
* Use dpkg --fsys-tarfile instead of ar for extracting files from deb
packages. The previous invocation could have failed for packages using
something other than gzip compression.
Patch from Ian Campbell.
i386 Xen guests require a PAE (686-bigmem) kernel in order to
run. Therefore this variant includes the relevant installer kernel and
ramdisk in install.386/xen as well as suitable kernel udebs and proper
debs for the installed system.
amd64 Xen has no similar requirement but we include the kernels under
install.amd/xen in order to have a consistent path under both
architectures.
Only do boot disk stuff for x86 and alpha if the image is supposed to be
bootable. For i386 and amd64 this avoids downloading D-I images for all
30+ CDs in a full set.
Adjust x86 boot scripts for new version (2.0) of framework in D-I for
creation of syslinux configuration files. Essentially the new version
is a backport of what was already implemented in debian-cd before the
release of Lenny and allows a significant simplification.
There are no significant changes in generated CD/DVD images.
