I was just going with the default behaviour of the tools, I can add
the '-k' argument to all of them to keep the uncompressed file.

local.conf could hold settings which relate to the distro or other
layers so I wouldn't want to write a script which directly edits it. I
think a well-documented sample file would be a good idea. Probably
can't call it local.conf.sample as it would only relate to raspberrypi
settings and the intention would be that you create your local.conf
from local.conf.sample and from this new file.
