# pbuilder-uml.conf(5)

configuration file for user-mode-linux port of pbuilder

## 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

- **UML\_BROADCAST***=255.255.255.255*

  Guest OS broadcast

- **UML\_GATEWAY***=192.168.0.1*

  Guest OS gateway

- **PBUILDER\_UML\_IMAGE=***${HOME}/uml-image*

  Guest OS file system image.

- **UML\_MOUNT\_TMPFS=***no*

  Whether to mount tmpfs inside the guest image. This is probably mostly useless.

- **BUILDPLACE=***${HOME}/tmp/*

  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.

- **UML\_MEM=***128*

  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.

- **UML\_BUILDRESULT=***/directory/of/build/result*

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

- **ROOTSTRAP\_IMAGESIZE=***size-in-megabytes*

  The size, in MB, of the disk iamge to create. Defaults to 1000.
