Package: systemd
Version: 215-7
Severity: normal

Dear Maintainer,

    * What led up to the situation?
Recently updated, and now boot hangs on LSB job "raise network
interfaces". Waited several minutes and still hanging. Says it has no
limit.
    * What exactly did you do (or not do) that was effective (or
      ineffective)?
Plugging in cable made it work. No cable it hanged. interfaces file had
allow-hotplug, and NOT auto
    * What was the outcome of this action?
When I commented out allow-hotplug, booted fine, with and without cable.
With allow-hotplug, cable had to be in, otherwise would hang.
    * What outcome did you expect instead?
Boot to happen with no delay, even if no cable plugged in.

Maybe similar to bug #754218?

My interfaces file is now:


# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
# BUG: commented as hung on boot
#allow-hotplug eth0
iface eth0 inet dhcp

iface wlan0 inet dhcp
	wpa-essid "redacted"
	wpa-psk "redacted"
