Bug Description

In raring, highbank has switched to using the "generic" kernel flavor. This will require some changes in MAAS - at least in maas-import-pxe-files.

In raring+ the arm kernel is armhf/generic instead of armhf/highbank. This means that maas needs to be able to also handle armhf/generic

[Test Case]
1. Install maas
2. maas-import-pxe-files
3. Check that armhf/generic kernel is downloaded.

[Regression Potential]
Minimal. It only allows armhf/highbank kernel to be downloaded and allow the tools to handle it.

One note to keep in mind - though the "generic" kernel may support other subarchitectures in the future, there will still need to be multiple kinds of boot files (vmlinuz vs. uImage - and perhaps even multiple uImages?) that will require us to retain some subarchitecture-specific knowledge.

I have been unable to use MAAS to construct an HPC cluster because of this bug. Does anyone know a work-around on this?

Downgraded to 12.04 for now and the problem is fixed - will look to upgrade back to 13.x when this issue is resolved. Thanks! :)

I managed to workaround this bug by:
1- adding "armhf/generic" to the list of the downloader architectures in /etc/maas/import_pxe_files
2- fixing the /usr/sbin/maas-import-pxe-files script so that it copes with "armhf/generic": http://paste.ubuntu.com/6213969/
3- running the fixed /usr/sbin/maas-import-pxe-files
3- "fixing" the directory layout by doing this: http://paste.ubuntu.com/6213976/
