# If there is a 'locale.gen' file in the profile (rootoverlay/etc/locale.gen)
# it will be used for the generation, otherwise the existing '/etc/locale.gen'
# (in the system to be larchified!) will be used, which is empty by default.

# $1: path to system to be larchified ("" if running system)
# $2: path to temporary overlay directory (where the overlay is being built)
