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.
AFAICT this option does not do anything: we're already booting from
CD-ROM at this point. If it were needed, it should also have been
included in the other append= lines.
Some udebs that no longer exist are removed and new (in some cases not
really new, but well) udebs that are known to be included in the initrd
are added. For i386 and amd64 the list of kernel udebs already included
in the initrd is updated.
+ Remove binary blobs from the package; pull those files from the
.debs in the archive as needed (isolinux.bin, vesamenu.c32)
+ sbm.bin *not* yet worked out, so drop it for now
+ Pull out the code to find the right deb and put it in a new helper
shell script (tools/which_deb), called from Makefile and boot-* as
needed.
- exclude any libdirectfb udeb instead of particular version
- exclude kbd-udeb and console-setup udebs (not yet used)
- remove strange comment about apt-setup; it seems like they have never
actually been excluded
- Structure of D-I images was simplified, so adapt to that
- Fix some broken references to etch in lenny boot-sparc script
- Hope after all this things will still work...
