Installing sys-apps/net-tools-1.60_p20120127084908 breaks the network configuration over ifconfig in openrc (possibly any version). The cause is that the ifconfig.sh module from openrc ( /lib64/rc/net/ifconfig.sh ) searches for the ifconfig executable in /sbin . Installing the net-tools in the above version, moves ifconfig from /sbin to /bin . So the ifconfig module from openrc is disabled, and you get some mysterious error messages like "executable _exists not found" this funktion and some others will be exported by the ifconfig.sh module from openrc if and only if the ifconfig executable is found in /sbin (see line 6 in ifconfig.sh). A simple ln -s /bin/ifconfig /sbin/ifconfig let the network setup works again. For my opinion either the ifconfig.sh module from openrc should search on both locations or a symlink should be created by net-tools. Without any modification not network came up including the lo interface. Best reagards Martin
upgrade openrc. search bugzilla next time (also closed bugs). *** This bug has been marked as a duplicate of bug 407757 ***
