Workaround to speed boot times for BBB debian image

[Gunjan Gupta]

Hi,

I noticed that BBB takes around 1 and half minute to finish the boot process because of /etc/init.d/networking service taking too much time to execute. I did some modifications into the networking script and the boot time reported by systemd got reduced to about 5 secs while the network becomes available in less than 15 seconds.

I have made the changes in the start procedure as follows

start)
        if init_is_upstart; then
                exit 1
        fi
        process_options
        check_ifstate

        if [ "$CONFIGURE_INTERFACES" = no ]
        then
            log_action_msg "Not configuring network interfaces, see /etc/default/networking"
            exit 0
        fi
        set -f
        exclusions=$(process_exclusions)
        log_action_begin_msg "Configuring network interfaces"
        if [ -x /sbin/udevadm ]; then
                if [ -n "$(ifquery --list --exclude=lo)" ] || [ -n "$(ifquery --list --allow=hotplug)" ]; then
                        udevadm settle || true
                fi
        fi
        # Lets run this if block in background to speed the boot process
        ( if ifup -a $exclusions $verbose && ifup_hotplug $exclusions $verbose
        then
            log_action_end_msg $?
        else
            log_action_end_msg $?
        fi ) &
        ;;

I know its a ugly hack but speeds up the process. I know installing some other softwares like connman, etc also speeds up the process but I didn't wanted to install them. Any other suggestions are welcome.

Which file is this ? ALso this looks to be an Ubuntu fix only ? Pretty sure Debian doesn't use upstart ;)

Yeah never mind about the Ubuntu stuffs. My eyes in the morning are not that great.
