When we've got multiple copies of the same initramfs hard-linked
together, gzip gets unhappy when we start modifying things
later. Explicitly break the links to fix that.
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.
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. :-)
tasksel now allows selecting the desktop, and d-i has dropped the boot
menu desktop selection, so we no longer need to have desktop boot
menus on CDs.
CD images for specific desktops (xfce/kde/mate/etc) should still
override the default tasksel desktop.
The code was assuming that the first line of output was something like
this (and this is the case of the cd builder machine that uses a custom
built xorriso):
> GNU xorriso 1.2.6 : RockRidge filesystem manipulator, libburnia project.
But the output of the version packaged in Debian does not have the GNU
string:
> xorriso 1.3.2 : RockRidge filesystem manipulator, libburnia project.
We fix this issue by extracting the version from the line starting with
"xorriso version" which does not have this discrepancy.
debian-installer now has extra steps to create a grub_embed file which
can be passed to xorriso's --embedded-boot option. Add corresponding
code in debian-cd to use it to make images USB bootable.
