cowbuilder

This is the tutorial for cowbuilder. See also [:qemubuilder: qemubuilder].

Usage

Initialization

Create the base image:

sudo cowbuilder --create

And a new and shiny build image is created in /var/cache/pbuilder/base.cow/

Every day usage

Update the base image

sudo cowbuilder --update

Build a package:

sudo cowbuilder --build somepackage.dsc

troubleshooting

Slow copying and removing of the COW directory

What cowbuilder does is:

cp -al /var/cache/pbuilder/base.cow /tmp/new
rm -rf /tmp/new

Of course cowbuilder uses a different location than /tmp/new. Try those commands and see how fast they are on your computer. You can compare them to our [:cowbuilder_benchmark: benchmarks].
