Description David Kovalsky 2009-02-18 08:55:41 EST
I've turned Network Manager off and wanted to bring up eth0 manually. 

# ifup eth0
Determining IP information for eth0.../etc/sysconfig/network-scripts/ifup-eth: line 290: 10371 Segmentation fault      /sbin/dhclient ${DHCLIENTARGS} ${DEVICE}


This happens only if selinux is in enforcing mode, permissive passes. Log:

That was catching me too, so no need to open a new bug
