hotplug isn't used on boot... it's called by the when it get "new device" events, like when you plug in a USB ethernet interface in a running system. hotplug has no concept of "boot". I disagree. Hotplug IS used at boot time with PCMCIA. I have a combo ethernet/modem PCMCIA card. It always stays in the laptop. It is my "eth0". At boot up, when PCMCIA is activated, hotplug gets a "new device" event. It then runs "ifup eth0" regardless of what my interface configuration file says (with ONBOOT). This is plainly wrong. The behavior of Red Hat 7.1 is DIFFERENT (in a worse, less flexible way) then that of 7.0, 6.2, 6.1, 6.0, 5.2, 5.1, 5.0, etc, etc. In all those previous versions of Red Hat, PCMCIA ethernet devices correctly honored the value of "ONBOOT". Don't get hung up on what you've called the variable. If you like, pretend it is called "ActivateInterfaceOnDection". I can verify that this is a problem for me as well... inserting the card ALWAYS brings it up, regardless of what ONBOOT says. Since there isn't a ONHOTPLUG setting, ONBOOT should be used. Traditionally ONBOOT has been used for device insertion, in all other version of Red Hat Linux that I can remember. The point is, to change this behavior in 7.1 is bad... because we go back to not having anything that control device insertion like ONHOTPLUG. A resolution for this could be creating a "ONHOTPLUG" variable, or we could simply use ONBOOT as we have all along (except in 7.1). Joshua Jensen joshua A partial fix is in hotplug-2001_04_24-8, initscripts needs to do the rest of the magic. Will be fixed in 6.12-1. |
From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3-12 i686) Description of problem: When you insert a network card. It is ALWAYS brought up. This is most annoying on a laptop. On a laptop with a PCCard/PCMCIA ethernet adapter, you could be plugging into many different networks. Because of this I have "ONBOOT=no" in my /etc/sysconfig/network-scripts/ifcfg-eth0 file. With Red Hat 7.1 and the default hotplug net.agent script, the ONBOOT setting is ignored. How reproducible: Always Steps to Reproduce: 1. Insert a PCMCIA/PCCard network card 2. Watch as ifup ethX is always run Additional info: Here is a patch against the net.agent in Red Hat 7.1 I noticed the rawhide net.agent is a bit different (the rawhide net.agent still ignores ONBOOT). --- net.agent-orig Thu Jul 5 12:07:50 2001 +++ net.agent Thu Jul 5 12:07:18 2001 @@ -53,7 +53,13 @@ exit 0 ;; *) + if LANG=C egrep -L "^ONBOOT=\"?[Nn][Oo]\"?" /etc/sysconfig/network-scripts/ifcfg-$INTERFACE >/dev/null 2>&1 ; then + exit 0 + else + exec /sbin/ifup $INTERFACE & + + fi ;; esac fi
