My system has booted up relatively fast while ran Debian 7 Wheezy, but after an upgrade to Debian 8 Jessie, and therefore from SysVinit to systemd, it became a way, way slower.

The thing slowing down the booting is network. The waiting for the upbringing of network interfaces exceeds 1 minute. I don't know what in the /etc/network/interfaces is affecting the boot up process, so here it is in its entirety.

/etc/network/interfaces:

allow-auto lo
        iface lo inet loopback

auto wlan0
        iface wlan0 inet static
                address 192.168.150.1
                netmask 255.255.255.0

auto eth1
        iface eth1 inet manual
                up ifconfig $IFACE 0.0.0.0 up
                down ifconfig $IFACE down

auto eth2
        iface eth2 inet manual
                up ifconfig $IFACE 0.0.0.0 up
                down ifconfig $IFACE down

auto eth0
        iface eth0 inet dhcp
                post-up brctl addbr br0
                post-up brctl addif br0 eth1 eth2
                post-up ifconfig br0 192.168.10.1
                pre-down ifconfig br0 0.0.0.0
                pre-down brctl delif br0 eth1 eth2
                pre-down ifconfig br0 down
                pre-down brctl delbr br0

Any suggestions how to boost things?

  • Actually I had issues where multiple services like samba, bind or lighttpd don't wait for network to be ready and start right away causing interface binding issues...

The solution is fairly easy, just replace auto to allow-hotplug. So I ended up with this:

allow-hotplug lo
        iface lo inet loopback

allow-hotplug wlan0
        iface wlan0 inet static
                address 192.168.150.1
                netmask 255.255.255.0

allow-hotplug eth1
        iface eth1 inet manual
                up ifconfig $IFACE 0.0.0.0 up
                down ifconfig $IFACE down

allow-hotplug eth2
        iface eth2 inet manual
                up ifconfig $IFACE 0.0.0.0 up
                down ifconfig $IFACE down

allow-hotplug eth0
        iface eth0 inet dhcp
                post-up brctl addbr br0
                post-up brctl addif br0 eth1 eth2
                post-up ifconfig br0 192.168.10.1
                pre-down ifconfig br0 0.0.0.0
                pre-down brctl delif br0 eth1 eth2
                pre-down ifconfig br0 down
                pre-down brctl delbr br0

Now system boots really fast.

I was having the same problem and the file names are slightly different.

Under /etc/network/interfaces.d (Note the .d) in the folder name. Inside the folder is the file "setup" which I changed "auto eth0" to "allow-hotplug eth0"

That seems to have worked:

auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp
