# This is a partial copy of uuid-runtime.postinst just to make sure #
# everyone gets their user renamed (even if they don't have uuid-runtime #
# installed). This package used to create the user in the first place, #
# but no longer uses it and all handling has been moved to uuid-runtime. #
# This (entire file?) should be dropped after this code has shipped in a #
# Debian Stable release (so we know everyone has been migrated). #
