stand-alone (slow) boot

Hi, I've got Arch installed on a R50p thinkpad.
Yesterday I booted stand-alone (no network cable attached) and I notices the boot pausing long on the "starting network".
Can this be tweaked? Can the "boot process" sence that there is no cable attached so you don't have to send the dhcp-client on a ghost-hunt.

Or is there a boot-parameter I can use. An extra lilo-entry dedicated for a quick stand-alone boot.

Re: stand-alone (slow) boot

I'm sure there are more ways but one quick solution would be to lower the timeout (-t) in /etc/conf.d/dhcpcd.

Re: stand-alone (slow) boot

add "@" before "network" in /etc/rc.conf, it will run dhcp in background

Re: stand-alone (slow) boot

Solved. It was another "it's all covered in Arch, just find out how" lesson for me.  Just activate the network-profiles as described here: "http://quiet.unixcorps.org/?p=5"

So I can boot "standalone" now. This triggers a next problem: In my rc.local I've added this

/usr/bin/ntpdate ntp.xs4all.nl

Right! I don't want that when I boot standalone, so I've got to  code this within a conditional block....
My solutution would be to grep the output of ifconfig and look for 'eth0'. If not found not execute the ntpdate.

But.... I'm sure there is a more elegant solution. Any ideas?

Re: stand-alone (slow) boot

I'd just add "&" to the end of the line - if it can't connect, it'll timeout.

Re: stand-alone (slow) boot

Remove the call from rc.local, modify /etc/conf.d/ntp-client-conf, and add "@ntpdate" to your DAEMONS in rc.conf.

Re: stand-alone (slow) boot

Still not perfect
In the old situation (rc.conf) I had eth0 as DHCP client and lo=localhost bound to 127.0.0.1 (how basic can you go?)
In the new situation (network menu at boot) I cannot get localhost running. Does somebody have a very basic working network-profile for me?
just :
- set hostname
- use localhost
- use eth0 as dhcp client

Re: stand-alone (slow) boot

use ifplugd, and don't start eth0 on boot.

lo="lo 127.0.0.1"
eth0="dhcp"
INTERFACES=(lo)
DAEMONS=( ... network ... ifplugd ... )
