Package: ifupdown Version: 0.7.54 systemd has always been hanging on my laptop at "Starting LSB: Raise network interfaces....", for about 2 minutes at each boot. Disabling dhcp and commenting some "allow-hotplug"/"auto" lines in the interfaces file didn't help, and booting with "systemd.log_level=debug systemd.log_target=kmsg log_buf_len=1M" didn't reveal anything.
Finally I added "set -x" to /etc/init.d/networking and found it's the "udevadm settle" command hanging the boot. Its default timeout is 2 minutes. The log is included below. Commenting out the line makes the system boot quickly. I don't know what its purpose is or how to figure out why it's hanging. Until it's fixed, I'd suggest logging a message before running the command and logging "Configuring network interfaces..." only after it completes. Maybe a shorter --timeout option would be a good idea too. - Michael -- Logs begin at Mon 2015-11-02 08:56:55 EST, end at Mon 2015-11-02 09:29:15 EST. -- ...
