Steve pointed out that this lookup is only here so that helper scripts
can grab those sources and make them available in a public location
such as http://cdimage.debian.org/cdimage/cd-sources/. The sources are
not embedded in the generated ISO and are thus not strictly needed
for building the ISO image.
This should happen even when we're not building source ISOs but it's
not needed if we don't have any similar policy in place. Thus CONF.sh
is now leaving $ARCHIVE_EXTRACTED_SOURCES unset by default and the
source will only be looked up if that value is set.
had a limited set of hard-coded menu entries - this was buggy and
didn't take into account all the possible boot variations. Now parse
the isolinux menus already provided in the d-i build and generate
equivalent grub menus, complete with themes for a reasonable layout
with graphics and titles.
+ Pull in grub-efi for amd64 and i386
+ Lots of extra code in boot-x86:
- pull grub EFI pieces out of the latest debian-cd_info.tar.gz
blobs in d-i, if they're there. If so, use them to make x86 images
bootable via EFI (both via CD and USB)
- generate boot entries for grub on the fly; temporary code for now,
will switch to parsing the isolinux entries shortly instead.
- depending more and more on xorriso rather than genisoimage...
