live-wrapper - RFE - Arch boot automatic detection
1) I make the assumption that live-wrapper currently supports to build
an x86 system with both a 586 kernel and amd64 kernel in the same iso.
2) I would like live-wrapper to have support for arch automatic
detection at boot. That means that the bootloader chooses the right
kernel depending on the available architecture.
I already did this work for live-build and the commits can be found here:
https://github.com/adrian15/live-build/commit/5852a69976da36abd7bcbbce95807a7a2451a7a6
https://github.com/adrian15/live-build/commit/36f781c4dc55e9a0d14cc74df5ff36f9eac2e33f
3) I don't mind implementing the bits to improve the grub cfg file and
live cfg file but taking a look at:
https://anonscm.debian.org/cgit/debian-live/live-wrapper.git/tree/lbng/vm.py?id=4c908cd1682f5d15912810a33c71c35a54fc7115
where the detect_kernel function is defined and:
https://anonscm.debian.org/cgit/debian-live/live-wrapper.git/tree/lbng/grub.py?id=4c908cd1682f5d15912810a33c71c35a54fc7115
which it's one of the places where it is used... well...
I need not only what you currently save on version but also the arch...
not sure how irl wants to implement it, with two variables,... Should I
parse myself the detect_kernels output and play from there? Should the
output be two variables ? A dict variable ?
Given these files found:
vmlinuz-3.16.0-4-amd64
vmlinuz-3.16.0-4-586
vmlinuz-3.14.0-1-amd64
vmlinuz-3.14.0-1-586
I need to be able to loop over 3.16.0-4 so that I found that it has two
architectures. Then if one of them is amd64 I guess I can suppose the
other one would be 586.
Once that happens I can add my auto entry which if it was a function
would need to know the kernel filenames and the kernel associated arch.
Additional note: Pae can also be supported by autodetection if pae
kernels are still available in Debian. I think pae it's supported on
syslinux but not on grub2.
4) Hopefully this RFE can improve the current live-wrapper design.
