cowbuilder (8)

cowbuilder [commands] [options]

cowbuilder Executes the specified pbuilder operation with cowdancer

Most commands invoke pbuilder with the specified commands, see pbuilder manual for details.

--create

Create the base.cow image. The directory for base.cow should be empty, or this command will fail.

--update

Update the base.cow image.

--build .dsc-file

Build a package given a .dsc file

--login

Start a session within the base.cow.

--execute

Execute a command within the base.cow.

--dumpconfig

dump configuration information.

Most options are the same as pbuilder, except for the following which are handled specially

--buildplace

The place where COW operation takes place.

--basepath

has a very different meaning to basetgz option of pbuilder, since there is no tgz. This option specifies the directory in which the COW master data is stored, the default being /var/cache/pbuilder/base.cow

--configfile [configuration file to load]

Additional configuration file to read after all other configuration files have been read.

--no-cowdancer-update

Do not use cowdancer on cowbuilder --update. Please use this option when cowdancer is interfering with upgrade process, or cowdancer itself is being upgraded within chroot.

--debian-etch-workaround

Work around on Debian etch compatibility. cow-shell will search for all files in chroot, but will work.

cowbuilder reads the following configuration files per default.

/usr/share/pbuilder/pbuilderrc

Application default, not to be changed.

/etc/pbuilderrc

System-wide default.

~/.pbuilderrc

User default

anything specified with --configfile option

Additional configuration at runtime.

The possible configuration options are as follows. Others are ignored.

DISTRIBUTION=distribution

NO_COWDANCER_UPDATE=1
