Bug#338431: linux-2.6: [infrastrucutre] gencontrol.py should know how to exclude stuff from deps, add INITRD_CMD setting.

[Sven Luther <luther@debian.org>]

Package: linux-2.6
Severity: normal


Well, this is something that came up with the desire of not using the
(currently broken) initramfs-tools on alpha. We need two implementations to
fix this, or at least one of them but the other seems useful too.

  1) gencontrol.py should know how to handle an 'excludes' field, which will
  be used to remove any reference to the entries in it when generating the
  depends and such fields, this would be used as : 

  arch/alpha/defines:
    ...
    excludes: initramfs-tools

  and the line : 

    Depends: yaird | initramfs-tools | linux-initramfs-tool, module-init-tools (>= 0.9.13)

  would be rewritten to :

    Depends: yaird | linux-initramfs-tool, module-init-tools (>= 0.9.13)

  2) We need support for setting INITRD_CMD prior to the make-kpkg command
  which creates the postinst (i thinkg the kernel-image one not sure though).

  This would allow to do :

  arch/defines :
    ...
    ramdisks: mkinitrd.yaird mkinitramfs

  arch/alpha/defines : 
    ...
    ramdisks: mkinitrd.yaird

The first one would be nice to have, we currently keep the full depend and add
a conflict on alpha, but i believe the second solution is better, altough it
needs k-p 10.000x. The reason why the second fix is better, is that there is
really no reason to stop alpha from installing initramfs-tools, just we have
to make sure not to use it by default.

Friendly,
