1866	"Pointless warning when running ""ifdown"" for a manually-configured interface"	alexander@…	lfs-book@…	"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."	task	closed	lowest		Book	SVN	normal	worksforme
