NAME

cowbuilder − a pbuilder wrapper for cowdancer.

SYNOPSIS

cowbuilder [commands] [options]

DESCRIPTION

cowbuilder Executes the specified pbuilder operation with cowdancer

COMMANDS

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.

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

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.

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.

CONFIGURATION FILE OPTIONS

The possible configuration options are as follows. Others are ignored.
DISTRIBUTION=distribution
BUILDRESULT=directory
BUILDPLACE=directory
BASEPATH=path
MIRRORSITE=http://mirror
NO_COWDANCER_UPDATE=1

See --no-cowdancer-update

DEBIAN_ETCH_WORKAROUND=1
