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.

DISTRIBUTION=distribution

BUILDRESULT=directory

BUILDPLACE=directory

BASEPATH=path

MIRRORSITE=http://mirror

NO_COWDANCER_UPDATE=1

EXAMPLES

cowbuilder --create

Create a base.cow image.

# cowbuilder --create --hookdir /usr/share/doc/pbuilder/examples/workaround/ --distribution etch --debootstrap debootstrap --basepath /var/cache/pbuilder/base-test.cow
bash: /root/.pbuilderrc: No such file or directory
W: /home/dancer/.pbuilderrc does not exist
 -> Running in no-targz mode
Distribution is etch.

cowbuilder --update

Update the base.cow image. # cowbuilder --update bash: /root/.pbuilderrc: No such file or directory -> Copying COW directory -> Invoking pbuilder W: /home/dancer/.pbuilderrc does not exist -> Running in no-targz mode -> copying local configuration -> mounting /proc filesystem -> mounting /dev/pts filesystem -> policy-rc.d already exists Refreshing the base.tgz -> upgrading packages . .

cowbuilder --build test_0.1.dsc

Build the package specified in dsc file, with the base.cow image.

pdebuild --pbuilder cowbuilder

Run cowbuilder --build against the current directory. The current directory should be an extracted Debian source package directory. Edit /etc/pbuilderrc to have PDEBUILD_PBUILDER=cowbuilder to make this the default behavior for pdebuild.

cowbuilder --login --bindmounts /home/dancer

Start a cow-shell session inside base.cow, with /home/dancer being bind-mounted to within chroot. Note that cowbuilder will not cow-protect what is inside /home/ # cowbuilder --login --bindmount ${HOME} bash: /root/.pbuilderrc: No such file or directory -> Copying COW directory -> Invoking pbuilder W: /home/dancer/.pbuilderrc does not exist -> Running in no-targz mode -> copying local configuration -> mounting /proc filesystem -> mounting /dev/pts filesystem -> Mounting /home/dancer -> policy-rc.d already exists -> entering the shell #

cowbuilder --create --distribution sid --basepath /var/cache/pbuilder/base-test.cow
