[cfergeau]

The kernel most likely needs to be gunzipped before being added to the bundle?

[praveenkumar]

@cfergeau Yes, I am thinking to create another issue for that. If we can extract the kernel and add it to the bundle for all arch and that could works then better to do it for all arch.

[cfergeau]

These changes are in #503 , uncompressing the kernel is cfergeau@07c6a4c

[praveenkumar]

Closing this one since this is also now fixed.
