+ Makefile: Add support for overriding the MKISOFS and MKISOFS_OPTS
variables on a per-arch basis
+ CONF.sh: add working examples for this
+ tools/boot/squeeze/boot-x86: if configured to use xorriso, add the
extra command line options to add the isohybrid MBR. Also work
around a difference in ISO directory naming between genisoimage and
xorriso.
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.
+ Add "FORCE_FIRMWARE=1" to CONF.sh to turn this on
+ Will pick up on packages in the "firmware" task and install them
+ Will also add sym-links to them in CD1/firmware so that new d-i code
can find them easily.
+ Will add a short sentence into README.html/README.txt
* Add top-level control of which checksums are desired for output images
see the CHECKSUMS setting in CONF.sh
* Fix some bashisms in tools/apt-selection.
The old setup worked fine with an ext2 initrd but fails with an initramfs,
either because autodetection is different for initramfs or because of kernel
changes (I suspect the first).
This means that booting s390 from CD has not worked since sometime during the
Etch release cycle, even though support for booting from CD was only added
early in that cycle - ouch.
For booting with an initramfs initrd we apparently need to specify its
offset and size at specific memory locations.
Change is based on SuSE's CD boot. Many thanks to Adam Thornton, Mark Post
(of Novell) and Bastian Blank for providing the pointers to the missing bits.
This fixes booting from CD using the d390.ins file; tested in Hercules for
both Lenny (31-bit kernel) and Squeeze (64-bit kernel).
Booting from CD using the d390.tdf file may still be broken (if possible at
all) as I have no idea how to test that.
