Another possibility is that the timeouts:
/etc/sysconfig/network/config WAIT_FOR_INTERFACES="30"
/etc/sysconfig/network/dhcp DHCLIENT_WAIT_AT_BOOT="15"
are not sufficient for your setup. When the dhcp client needs
too long to setup the interface, /etc/init.d/network will
continue and report "in background".
Common reason is a bridge with enabled STP. Please verify that
all your bridges have this two settings in ifcfg-* files:
BRIDGE_STP='off'
BRIDGE_FORWARDDELAY='0'
A bridge with enabled STP may need up to 50 secs before it
enables the interface / starts to forward packets, see also:
http://tldp.org/HOWTO/BRIDGE-STP-HOWTO/advanced-bridge.html#STP
you can tune STP e.g. using
BRIDGE_FORWARDDELAY='4'
BRIDGE_HELLOTIME='1'
BRIDGE_MAXAGE='4'
and increasing the timeouts to:
WAIT_FOR_INTERFACES="60"
DHCLIENT_WAIT_AT_BOOT="30"
When the ISC dhclient is in use (not dhcpcd), if may need +15sec:
# Note: RFC 2131 specifies, that the dhcp client should wait a random time
# between one and ten seconds to desynchronize the use of DHCP at startup.
