Description of problem: When restarting network, script exits with [FAILED] error on eth0. Version-Release number of selected component (if applicable): net-tools-1.60-84.fc8 How reproducible: Always Steps to Reproduce: 1. start netplugd daemon `service netplugd start` 2. try to restart the network `service network restart` Actual results: Restarting network produces the following: [root@carlos ~]# service network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: Determining IP information for eth0...dhclient(6308) is already running - exiting. This version of ISC DHCP is based on the release available on ftp.isc.org. Features have been added and other changes have been made to the base software release in order to make it work better with this distribution. Please report for this software via the Red Hat Bugzilla site: http://bugzilla.redhat.com exiting. failed. [FAILED] ============================================================ *Note - if netplugd is stopped, script exit code is correct ============================================================ Expected results: Correct exit code, since the interface restarted correctly and network is available Additional info: possibly related to: #242916 and #242918 (logged against net-tools) and 237978 (against dhcp, RHEL5)
in net-tools package, only the way network is tested in netplugd was changed. This should affect the start of network itself.

netplugd starts its own dhclient, correct? Ergo, attempting to use it with manual up/down of interfaces is unlikely to DTRT.
