I have finished LFS (Linux From Scratch)
I built it inside a root_fs.

LFS uses udev (I dont know if this important to what I will say).

At host:
linux eth0=slirp,,/usr/bin/slirp

If I run at uml:
ifconfig -a:

dummy0    Link encap:Ethernet  HWaddr 0A:B0:8B:18:84:A1  
          BROADCAST NOARP  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

eth0      Link encap:Serial Line IP  
          NOARP  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:256
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Interrupt:5

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)



There is a dummy0 with mac address and eth0 has not one.
The mac address of dummy0 changes all the times that I boot uml.

If I put ifconfig eth0 10.2.0.15 up, this ip appears in eth0.

What can I do?
