 qemud-tap 
- helper to create a tap network device
 qemu-tap 
is a helper program to create a tap network device for bridge
devices. This is the preferred method in qemu-init. For each bridge
device there will be a symlink  qemud-<bridgedev> 
, where 'bridgedev' is
the name of the bridge device. Example: if your bridge device is br0 the
symlink is  qemud-br0 
.
Howto create a network bridge is outside the scope of qemu-init. Right now
there will be one bridge device respected automatically only. This will may be a
subject to change in the future. Different bridge devices have to be configured
in  <name>-qemu.cfg 
. Example:
    -device virtio-net-pci,netdev=net0,mac=DE:AD:BE:EF:06:2F
    -netdev tap,id=net0,script=/home/srvcs/qemud/lib/qemud-\fIbr1\fR
