# derive_language_layers minimal desktop-minimal desktop-minimal-default-languages
# derive_language_layers minimal.standard desktop desktop-default-languages
#
# The way this works is perhaps a little counterintuitive.
#
# The first goal here is that the installed system should contain
# language support for the language the user selected. One way to do
# this using layers would be to have a layer that contained no
# language support and a derived layer for each (default) language. So
# something like:
#
# filesystem.squashfs (contains no language support)
# filesystem.en.squashfs (contains English language support)
# filesystem.fr.squashfs (contains French language support)
# ...
#
# Then if the user selects French as their language, we just copy
# filesystem.fr.squashfs to the target system.
#
# But we want the live session to support these languages too and
# simply adding all the language support to the live layer would mean
# we'd have the each language's support files on the ISO twice (once
# in filesystem.$LANG.squashfs and once in filesystem.live.squashfs).
#
# So what is done instead is that we add support for all the default
# languages to the base layer and then create derived layers that
# _remove_ support for all languages but the desired language and
# because file removals are cheap to represent in overlays, this all
# ends up taking way less space, and filesystem.live.squashfs gets
# support for all languages from the base layer. We also create a
# layer than has support for all languages removed, which can be used
# for the base of an install for a non-default language.
