that the kernel knows this information. It's going to take me a lot

A uml file system is most normally an ext3 (or some other fs) image
plus a cow file (for local writes). You could just export the
filesystem.
Alternately, standard backup tools would do the job.
UML in a terminal with it's console set to terminal, eg:
umlkernel ... con0=fd:0,fd:1
and then send us the output that appears in the terminal it would be a
help.

get it to stop listening for DHCP on 0.0.0.0.
However, there is another reason for using a separate DHCP
server. It's tied to the tap interface being used for the UMLs. When
you take the interface down the dhcp server should go down as well.
Nic
answer to blaisorblade.
dnsmasq only has one config option for defining the listening address
so I can either have my dns only on the private lan and dhcp working
or have my dhcp on the public lan with all the problems that my bring.

I don't dhcp can _match_ on a sent hostname but it can on a
dhcp-cl
can forward from the UML to the host,
you can't reach other hosts on the host's network; in other words "why
do you need a bridge?". Certainly, my UMLs don't seem to be able to do
that.

It did... I couldn't figure out the problem at all... so I started

And now I've fixed it.
I think that I may have left a host based loop back mount to the UBD
open while I mounted it in the UML and that of course is bad.
Anyway... it's working now.
