NAME

       pbuilder-uml.conf - configuration file for user-mode-linux port of pbuilder

DESCRIPTION

       /etc/pbuilder/pbuilder-uml.conf contains default values used in pbuilder-user-mode-linux program invocation.

FORMAT

       MY_ETH0=tuntap,,,192.168.0.2
	      Configures ethernet setting used for booting linux.  See how rootstrap boots your system, and copy that.

	      Specify --eth0=slirp,12345,/usr/bin/slirp-fullbolt to use the slirp connection.

       UML_IP=192.168.0.3
	      IP address to use for guest OS.

	      This can be set to dhcp for obtaining IP address through DHCP.

       UML_NETMASK=255.255.255.0
	      Guest OS netmask

       UML_NETWORK=192.168.0.0
	      Guest OS network

	      The  location  which build will take place.  pbuilder-user-mode-linux will place temporary COW files to there.  The user running UML
	      needs to be able to access that directory.

	      The amount of memory allowed for UML.  Give more value to here.

       UML_HOSTNAME=uml-host
	      The hostname for the UML.

	      The hostname should be available in /etc/hosts so that hostname -f will be able to return the FQDN.

	      The directory where build result of pbuilder-user-mode-linux is stored.
