When (manually) using network namespaces with a virtual ethernet pair (veth), I want to make NM ignore all veth devices.

Currently I have this configuration (limited to just 4 pairs or 8 interfaces):

    unmanaged-devices=interface-name:veth0;interface-name:veth1;interface-name:veth2;interface-name:veth3;interface-name:veth4;interface-name:veth5;interface-name:veth6;interface-name:veth7

It would be great if I could use glob patterns:

    unmanaged-devices=interface-name:veth[0-9];interface-name:veth[0-9][0-9];interface-name:veth[0-9][0-9][0-9]

or just a single wildcard:

    unmanaged-devices=interface-name:veth*

bug 731014 makes it possible to use udev rules which would help too, but implementing wildcards is probably easier.
