network.service took about 22 seconds to become active.

Yes I gathered that from what I saw when booting 13.1 Beta.

The question, of course, is what exactly, and why, should be taking so
much time to activate the network. I am not using the new Network
Manager (as far as I know) and there is nothing special about my setup -
a wired modem/router with 2 computers on the LAN.

That question becomes 'what does it depend on?'

It could also be 'what actually does 'network.service' mean?
Does it just mean the Ethernet connection to the LAN?
Or does it include the network SERVICES such as DNS/NAMED, any routing
protocols and more?


On my server DNS takes a long time to start because, as I've written
before, I have the huge table from
http://pgl.yoyo.org/as/serverlist.php?hostformat=bindconfig&showintro=1&mimetype=plaintext


which takes a few tens of seconds to digest.

Sensibly, DHCP depends on having DNS up so that it can tell the DNS
server about hosts that now have an IP address that wasn't in the
original. Until DHCP is up no other hosts on the LAN get an IP
address :-(

Until DNS is up the mail subsystem can't work.

Until DNS is up SpamAssassin can't work so fetchmail can't work.

And so it goes.


So the question becomes 'what does it depend on?'

What are your dependencies?
Does the chart show them?

The answer to your last 2 questions is simple: I don't know - you'll
have to educate me :-) .

If I sent you the graph which I just generated perhaps you could tell me
what it shows? The file is 427Kb big so I won't send it unless you OK it.


It is not the question of dependencies. You have single service that
takes this time to start.

The first obvious question - are you using ifup or NetworkManager.
