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, 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
