#1866: Pointless warning when running "ifdown" for a manually-configured
interface

For the LiveCD needs, LFS network bootscripts have to be modified for
compatibility with the "hibernate" script. The issue is:
* The LiveCD has to run dhcpcd by default on all network interfaces,
because it is not known which of possibly more than one network card is
connected to a switch. Current syntax of network configuration files
doesn't allow this, and the LiveCD has to bypass the existing
infrastructure and run dhcpcd from udev rules in order to accomplish the
goal.
* Because of that, some interfaces may be up, but without valid
configuration files (I refer to such interfaces as manually-configured
below, because exactly the same situation arises when one runs the "ip"
command manually).
* The "hibernate" script wants to "ifdown" all interfaces, but doing so
for interfaces without the configuration file results in a pointless (in
this situation) warning. A similar warning appears when resuming, when the
"hibernate" script runs "ifup". This warning has to be invisible in this
case.
Of course, the LiveCD can create an interface configuration file and run
"ifup" instead of running dhcpcd directly, but the bug is still relevant
for manually-configured interfaces: not everyone discovers net-setup, and
some people configure static IP addresses manually by the "ip" command.
Text of the warning:
{{{
/etc/sysconfig/network-devices/ifconfig.eth0 is not a network
configuration file or directory.
}}}
So the bootscripts should provide some means (environment variable or
ifup/ifdown command line switch to be used by the "hibernate" script) to
suppress this pointless warning.
