Bug#757697: RFE: Autodetection of architecture at boot time to load appropiate kernel

[Adrian Gibanel Lopez <adrian15sgd@gmail.com>]

Source: live-config
Severity: wishlist

Dear Maintainer,

  If one has configured its Debian Live to have more than one architecture
kernel this is what I am expecting would be the default behaviour is:

* Add an auto entry
* Auto entry will either load the Kernel64 entry is a 64bit architecture is
detected or load the Kernel(not 64) entry is no 64bit architecture is detected.

* In order to achieve that behaviour:

** With GRUB2 you should use "cpuid -l" command as seen in Rescatux grub cfg
file:

http://sourceforge.net/p/rescatux/git/ci/a332cbb67e10e8cc3f73bcad8e4893c1acda115a/tree/rescatux_grub.cfg
Upstream documentation: http://www.gnu.org/software/grub/manual/grub.html#cpuid

** With Isolinux / Syslinux you should use the ifcpu64.c32 comboot module as
seen in tails:

https://git-tails.immerda.ch/tails/tree/config/binary_local-
hooks/20-syslinux_detect_cpu?id=deb15c765e2b34fe587c96ca590981a59a278922

Upstream documentation: http://www.syslinux.org/wiki/index.php/Ifcpu64.c32

Thank you!

P.S.: I'm not sure if live-config it's the right package. Was it to be live-
boot please change bug's associated package.
