Public bug reported:
It seems we've had code in livecd-rootfs for roughly forever to strip
.pyc files out of the squashfs included on desktop images. There is an
override to skip this for server and cloud images, but we discovered
this recently because the missing .pyc files on ubuntu-core images
causes very long start-up times for python apps on some armhf systems.
So the question is, is this still a sensible optimization on Ubuntu
Desktop images? It was done at a time when space was tight; that's much
less of a concern now than it was.
If this does still make sense for Desktop, we should probably at least
invert the logic to make this opt-in rather than opt-out so that new
image types on ARM don't get caught out with the problem.
