[pkg-dhcp-devel] Bug#800914: isc-dhcp-client: dhclient-script fails with /bin/sh=/bin/dash after latest upgrade

[Lorenzo Beretta]

Package: isc-dhcp-client
Version: 4.3.3-5
Severity: important

Dear Maintainer,

dhclient (invoked by wicd in my case) used to work until the last
upgrade, today it breaks because dhclient-script complains about
an illegal number at line 136:
        run_hookdir() {
            local dir
            local exit_status
            dir="$1"

            if [ -d "$dir" ]; then
                for script in $(run-parts --list $dir); do
                    run_hook $script
                    exit_status=$((exit_status|$?))
                done
            fi

            return $exit_status
        }
It seems that dash doesn't support var=$((var ... )) when var is unset,
so please init exit_status to zero.

Regards
