DESCRIPTION

cowbuilder Executes the specified pbuilder operation with cowdancer

COMMANDS

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

update, up, u

Update the base.cow image.

build, b

Build a package given a .dsc file

login, l

Start a session within the base.cow.

execute, e

Execute a command within the base.cow.

dumpconfig

Dump configuration information, used for debugging.

OPTIONS

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

The place where COW operation takes place.

--basepath

This has a very different meaning to the --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

Workaround for Debian Etch. cow-shell will search for all files in the chroot, but will work.

CONFIGURATION FILES

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.

DISTRIBUTION=distribution
BUILDRESULT=directory
BUILDPLACE=directory
BASEPATH=path
MIRRORSITE=http://mirror
NO_COWDANCER_UPDATE=1
