[Bug 623375] Re: Skipping the bootloader installation when creating rootfs or installation media

[Oliver Grawert]

just as a sidenote, ubuntu installs kernels in it's live images and
generates an initrd but does that in a completely controlled environment
by diverting update-initramfs to suppress the execution for triggers and
explicitly calling the diverted binary at some point in livecd-rootfs.
kernel and initramfs installation surely happen in all live or
preinstalled images on ubuntu.

currently ubuntu is just in the lucky situation that our imx51 based
builders dont have a generic fallback [1] implemented at all and thus
simply dont execute flash-kernel.

if you run it on an architecture that has the defined generic fallback
implemented (dove and omap3 based systems) flash-kernel will simply try
to run that generic method on the hardware it runs on (the build
machine)

it seems to be an accidential omission in the spec that there is no way
to prevent the generic bootloader installation.
