This code was using "-efi-boot-part", which works fine for booting but
creates images that d-i can't use: only the full disk or the ESP
partition would contain working filesystems, and d-i doesn't like that.
Instead, switch to appending the ESP as an extra partition on the end
of the image. This will take a small amount of extra space, but will
at least work reliably!
Split the code up and use BOOT_EFI and BOOT_BIOS to control which
goes where. We now support:
* BOOT_BIOS=1 BOOT_EFI=0 for BIOS boot only via an ElTorito boot
record (like debian-cd used to be before EFI support was added)
* BOOT_BIOS=1 BOOT_EFI=2 for standard BIOS boot as
primary ElTorito boot record and EFI as an alternate ElTorito boot
record (common case, just like we've been doing for amd64 in
debian-cd for a while)
* BOOT_BIOS=0 and BOOT_EFI=1 for *only* EFI boot as the primary
ElTorito boot record (new case, might be useful for some
Macs *maybe*)
Set BOOT_METHODS in the debian-cd environment to determine which of
these cases is desired in a given build.
Also removed the support for the "old" syslinux packaging layout, it's
not been around for a while now.
Remove un-needed boot$N in the xorriso command line, we don't have
crappy BIOS lomitations.
Remove support for older xorriso versions.
Use new -efi-boot-part --efi-boot-image options to make an
isohybrid-style images with an explicit EFI partition. Will hopefully
make d-i happier with our images from USB.
Provide hashes for uncompressed Translation-* files, and remove the
uncompressed versions from the output disc. Closes: #767253. Initial
patch from Michael Vogt - thanks!
d-i has removed these files now, so don't look for them for kernel
params. Closes: #767223, #766411. Thanks to Prema and Vagrant for
(identical!) patches. :-)
