Package: ifupdown
Version: 0.8.35
Severity: normal

Dear Maintainer,

After fresh installation of Beowulf by Server ISO Beta 3,
/etc/init.d/networking hangs up at ifup wlan0.

/etc/network/interfaces is

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug wlan0
iface wlan0 inet dhcp
 wpa-essid MYESSID
 wpa-psk MY_WIFI_PASSWORD
# This is an autoconfigured IPv6 interface
iface wlan0 inet6 auto

"ifup" hangs up with the message
waiting for lock on /run/network/ifstate.wlan0

Detailed output with verbose=YES in /etc/default/networking is
attached as screenshot.

Then it times out. After login, "ip a" shows

root@devuan:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

       valid_lft forever preferred_lft forever

IPv4 nor v6 address is not configured. After "ifdown wlan0; ifup wlan0",
"ip a" shows:

Message #10 received at 463@bugs.devuan.org (full text, mbox, reply):

I found a workaround on this bug:
Changing

allow-hotplug wlan0
to
auto wlan0

surpresses this. Ryutaroh

Ryutaroh,

Thanks for this. Sorry for not replying -- I missed this report coming through.

This is a known issue an workaround. It only occurs if the ethernet cable is
plugged in before boot.

As well as your workaround there is a know initscript patch:

 https://dev1galaxy.org/viewtopic.php?pid=15493#p15493

It is already reported in Debian, but there is no sign of it being addressed.

 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=922550
 
We will add the workaround to the Release Notes and consider forking the
package.

Thanks

Mark
