Hi,
This is a small note to say that cowbuilder is now released, after
some coding and testing at Debconf in Mexico, and on the plane on my
way back. To use it, install pbuilder and cowdancer package.
apt-get install pbuilder cowdancer
Then create the chroot image in /var/cache/pbuilder/base.cow/ with
cowbuilder --create
You can update this image with
cowbuilder --update
To build a package,
cowbuilder --build XXX.dsc
or more simpler
pdebuild --pbuilder cowbuilder
or even more simpler
edit /etc/pbuilderrc to have PDEBUILD_PBUILDER=cowbuilder
pdebuild
Please share your experience with the world; cowbuilder code is pretty
preliminary and doesn't have some features; please do report if you're
dying to see a feature so that such feature will be likely to be
implemented first.
The rough time measurement results are below, in general, package
extraction used to take 1 minute for my package building; which is now
eliminated to improve speed:
