I'm seeing very slow startup on 3.8 latest when the lan cable is not connected. Does anyone know a solution?
Is this a boot on an already installed system you're talking about?
Or ....... the boot on the live system from USB (or DVD)?
In the latter case the live startup is slow due to it looking for wlan credentials on the the hard-drives.
The max probe time allotted is ~30 secs (too long IMO), after which it will continue to boot.
IMO it's an unneeded slowing down of the boot time and gives a bad impression of the speeds Elive is capable of......but hey, that's just me. 
It's an installed system, 3.8 with updates applied on good hardware.
With a lan cable connected, using dhcp, the startup runs straight through.
When the lan cable is disconnected (and wifi pre-configured) it takes about 90 seconds to reach the desktop screen.
I'm guessing the pause is dhcp related, it waits for the lan and then tries wifi.
Normal start time with lan cable connected is 33 seconds
To see what's going on during boot, find out the names of your network devices (in my case enp0s25 for LAN and wlp4s0 for WLAN) and then check dmesg for logs in relation to your hardware :
dmesg |grep wlp4s0 ... or whatever device you're looking for (like i.e your touchpad).
There might be some hints as to what's going on.
Or to scour dmesg page by page: dmesg | less
The startup waits for a dhcp timeout on the wired ethernet before attempting to try wifi, that is what is causing the long delay.
I don't know enough about systemd to workout if or how they can run in parallel. Can anyone share any insights?
If waiting for a LAN connection is the cause, it will show up in "dmesg".
Please back up your assumption with concrete logs.
There's simply no way to tell what's wrong with what you're communicating there. So be specific!
A 30sec error will definitely show in the logs.
I assume this issue only happens in Live mode, right? (should not happen when the OS is installed)
In any case is solved for the next build 3.8.24, betatests welcome
...and you're ignoring our feedback that 30s delay is way too much... 
The delay is confirmed in the logs as waiting for dhcp timeout before starting wlan search

This happens on installed to disk.
My understanding of systemd is that it should start eth & wlan at the same time. It waits for eth dhcp to timeout before wlan is started.
Thanks for a great system, I've been using it since gem.
Well actually your wlan is the first to get activated by the kernel.
at 13.00.25 interface wlp6s0 logs in to "mechtron" and is connected at 13.00.26
That's one second.
Then at 13.00.32 the lan inteface enps5s0 kicks in and drops again at 13.00.33 due to not receiving any DHCPOFFERS.
At 13.00.55 systemd tries enps5s0 again to no avail...and does indeed need almost 30secs to activate wlps6s0
It's strange that it's that persistent there. Could it be that it was used as the initial connection during setup/install and wlan setup later? 
If you've got a LAN cable plugged in, remove it to get some speed at boot or ...... have it connect to a properly set up gateway for dual connectivity.
..... Or disable the interface.
In comparison:
My (encrypted) Thinkpad X1Carbon boots up in 30secs....to a full desktop.
It looks like something broke in your network setup. At least I cannot replicate on my machines.
