Bugzilla Bug 143666

Booting with the new baselayout (at home, no router, I connect to the internet
using a DSL modem and rppppoek) and the following setting :
RC_COLDPLUG="no"
RC_NET_STRICT_CHECKING="no"

lets the boot process hang while starting cupsd. I have an USB printer attached
to the 2nd USB port of my hinkpad T41. At this point the USB mouse is also not
working. Fortunately I can login b/c kdm is started, no other login option is
possible at this point.

With 
RC_NET_STRICT_CHECKING="none"

the eth0 network is not brought up - with old baselayout I got at least a
static ip address at home.

here's the network config:

n22 /etc/conf.d # cat /etc/conf.d/net
# /etc/conf.d/net
#

config_eth0=(
        "dhcp"
        "192.168.0.254/24"
        )

dhcpcd_eth0="-t 6"
dhcp_eth0="nontp"

Setting
RC_COLDPLUG="yes"
I can boot my system without any obviously problems and have:
n22 /etc/conf.d # ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:0D:60:7B:2D:9B

With the following setting the "old" working behaviour is restored:

tfoerste@n22 ~ $ grep -e ^RC_COLD -e ^RC_HOT -e ^RC_PL /etc/conf.d/rc
RC_HOTPLUG="yes"
RC_COLDPLUG="no"
RC_PLUG_SERVICES="!net.eth0"


During boot process I can see the message that net.eth0 is starting, after 6
seconds it DHCPCD times out and a static address is assigned to that adapter.
After that the normal boot process continues (starting dnsmasq, apache2, snort,
....)

so what sort of kernel configuration do you have ?  are those things built as
kernel modules ?

Created an attachment (id=94113) [details]
kernel config

Right, built as much as possible as modules.
I attached my kernel config here.
Here are my init levels:

so let me see ... you have devices hooked up at boot, you have coldplugging
turned off, you have your kernel built as modules, and you're wondering why
things arent working ?

the point of coldplugging is to detect all the devices you had plugged in
already and load the modules for them

With the old baselayout I had
RC_COLDPLUG="no"
without any problems, that's why I used the same value for the new one.

Right, I've turned it on now.

My actual problem is to reproduce the behaviour that the boot process doesn't
continue after cupsd. (Un)fortunatly it's currently working (I'm not happy
about an issue which cannot be reproduced.

I'll close this bug until I can reproduce the hang on the boot process.
