Bug#790448: [systemd] Regression from 215-18: Shutdown delayed for minutes waiting for automounted CIFS

[Gavrilov Aleksey]

Package: systemd
Version: 215-17+deb8u3

Hi

An error occurs when the system boots.
Conditions for the appearance.
The main network interface is adapted to receive via DHCP using systemd.

cat /etc/systemd/network/00_eth0.network

/[Match] Name=eth0 [Network] DHCP=yes # <-----/

cat /etc/systemd/network/10_interface_mesh0_ipv4.network

/# Ansible managed: modified on 2016-01-29 17:12:05 /

/[Match] Name=mesh0 [Network] Address=172.16.35.5/24/ cat 
/etc/network/interfaces /# The loopback network interface auto lo iface 
lo inet loopback/

мар 24 15:41:56 itregion-gavrilov mount[701]: Refer to the mount.cifs(8) 
manual page (e.g. man mount.cifs)

I also read this thread here ( 
https://lists.debian.org/debian-user/2015/06/msg01545.html )
I found that the error only occurs if the configured network interface 
systemd dhcp.

Adding a script solves the problem, but it's clumsy solution.

[Unit]
Description=Waiting for CIFS server
DefaultDependencies=no
Conflicts=shutdown.target
Wants=network-online.target
Before=network-online.target shutdown.target
After=network.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/bin/sh -c "while ! ping -c 1 gw_ip >/dev/null; do sleep 1; done"
# Modify this timeout to your heart's content.
TimeoutStartSec=10

[Install]
WantedBy=network.target

I formed the opinion that Systemd not wait Dhcp-client when the network 
interfaces are configured through it.
