nrelease -- release building infrastructure
DragonFly provides a complete build environment suitable for users to
make full releases of the DragonFly operating system. All of the tools
necessary to build releases are available from the git repository in
src/nrelease. A complete release (that is, a live CD) can actually be
built with only a single command. This command is aptly named ``make
This document does not cover source code management, quality assurance,
or other aspects of the release engineering process.
The release Makefile (src/nrelease/Makefile) defines a number of targets
which are roughly modeled after the targets used for building the system.
help Offer some help.
release Builds world and kernel, installs them, adds packages and
prepares the ISO image.
quickrel Same as release but uses the quickworld target (alias
realquickrel Same as release but uses the realquickworld target (alias
clean Removes the ISO root directory and object files.
realclean Same as clean but also removes external packages.
The quickrel and realquickrel targets will only work if a full buildworld
and buildkernel have been done before. For a description of the corre-
sponding build targets, see build(7).
A number of additional targets may be specified along with release,
quickrel, or realquickrel to add additional features:
gui Adds Xorg(1) along with some additional applications to the
During the process of rolling a release a check is performed to find out
if external packages to be put on the CD exist on your system. If they
cannot be found, the release process will stop and give proper commands
for downloading and setting up these packages.
ISODIR Default prefix of ISOFILE and ISOROOT (default is
ISOFILE Name of the ISO image to generate (default is
ISOROOT Location where the image contents are installed to
before the ISO is prepared.
KERNCONF Kernel configuration(s) to use.
PKGBIN_MKISOFS Location of the mkisofs(8) utility which is to be
used during the build.
DPORTS_PACKAGES List of packages to be added to the ISO.
DPORTS_EXTRA_PACKAGES List of packages, in addition to DPORTS_PACKAGES,
to be added to the ISO.
DPORTS_PATH Location of the dports(7) tree to be used for
WITHOUT_SRCS If set, this variable will prevent source code
from being copied to the ISO image.
IMGFILE The name of the image file (default is
IMGMNT The mount point for the image (default is
IMGUSBDEV The disk device to use in the image's fstab(5)
(default is /dev/da8).
The following sequence of commands is used to build a standard
DragonFly 2.0 installation CD image (assuming that a local git repository
is available, see development(7) for how to get this):
git checkout -b rel2_0 crater/DragonFly_RELEASE_2_0
After running these commands, the image will be available in the
git(1), make(1), make.conf(5), build(7), development(7), dports(7)
The nrelease framework was added in DragonFly 1.0 to implement the idea
of a ``live CD''.
The nrelease infrastructure was written by Matthew Dillon. This manual
page was written by Sascha Wildner.
