I think the bug reporter suggest to replace the
system(...) == 0 or error("systemctl preset failed on $scriptname: $!");
with a more correct (and verbose)
system(...);
if ($? == -1) {
error("systemctl preset failed on $scriptname: $!");
}
elsif ($? & 127) {
error("systemctl preset died with signal " . ($? & 127));
}
else {
error("systemctl preset failed with return status " . ($? >> 8));
}
as `perldoc -f system` suggest. (Untested, so might contain typos and
the like.)
Currently it always give "$!" as the reason, even when not correct.
This would also be incorrect if the real systemctl is used if the
command fails because of syntax errors or so.
