Red Hat Bugzilla – Bug 30643
ONBOOT ignored for eth0 when eth0 is a pcmcia NIC
Last modified: 2007-04-18 12:31:57 EDT
The ONBOOT="no" option appears to be ignored for eth0 NICs which are
pcmcia adapters. The init scripts seem to ignore the eth0 interface
however the Red Hat pcmcia script /etc/pcmcia/network goes ahead and
brings it up anyway if the card is found in the socket at boot.
ONBOOT does seem to work for ppp0 where /dev/ttyS1 is a pcmcia modem in
slot 0. When ONBOOT="no" in ifcfg-ppp0 the device does not attempt to
start up even if it is in the slot at boot.
Laptop is an IBM Thinkpad T20 running Red Hat Wolverine (7.1 RC1) and the
stock initscripts / kernel / pcmcia packages.
This is normal behavior for PCMCIA/cardbus NICs.
How exactly is this normal behavior? If an interface is set to be ONBOOT="n"
it's expected that during boot that it won't come up.
The reason this happens in the first place is because of the custom Red Hat /
network script integration going on in /etc/sysconfig/network-scripts and
Before closing this as "not a bug" I think it needs more consideration. The real
soluton is better Red Hat / pcmcia integration. A hack job would be to document
that this is a problem and in the netcfg control panel make this option
unavailable if the interfaces is a pcmcia nick. (Possibly check /var/pcmcia/stab
While we're at it, why is it that networking starts before pcmcia services in
the first place? This seems to be a Red Hat only thing, but I could be wrong.
So can we please make /etc/pcmcia/network parse the
/etc/sysconfig/networking-scripts/ifcfg-if0 scripts instead of blindly bringing
up the interface?
It's normal behavior in that that's the way it's always been.
It's also the behavior you'll get from hotplug when that is used for
cardbus or pcmcia interfaces. In any case, this is not an initscripts
I do not expect this to be changed for this release.
