By the way in general about usr/share/rear/conf/GNU/Linux.conf

I wonder why therein new elements are appended
in different ways to existing arrays
sometimes as

ARRAY=( ${ARRAY[@]:-} new_element1 new_element2 ... )

and sometimes as

ARRAY=( "${ARRAY[@]}" new_element1 new_element2 ... )

or

ARRAY=( "${ARRAY[@]:-}" new_element1 new_element2 ... )

cf. usr/share/rear/conf/default.conf
https://github.com/rear/rear/blob/master/usr/share/rear/conf/default.conf#L19

# In general using ${VAR[*]} is problematic and using ${VAR[@]} without
# double-quotes is also problematic, see 'Arrays' in "man bash" and
# see https://github.com/rear/rear/issues/1068 for some examples.
