Comment 1 Yann Leprince 2017-12-04 09:15:25 UTC
This is due to using the operator == instead of = in the EPREFIX comparison. The checkbashisms tool finds another problem on the same line:

% checkbashisms /usr/sbin/     
possible bashism in /usr/sbin/ line 41 ($EUID should be "$(id -u)"):
if [ ${EUID:-0} -ne 0   -a   "${EPREFIX}" == '' ] ; then
possible bashism in /usr/sbin/ line 41 (should be 'b = a'):
if [ ${EUID:-0} -ne 0   -a   "${EPREFIX}" == '' ] ; then

So this line should be replaced by:
if [ "$(id -u)" -ne 0   -a   "${EPREFIX}" = '' ] ; then
