34.Dt NRELEASE 7
35.Os
36.Sh NAME
37.Nm nrelease
38.Nd release building infrastructure
39.Sh DESCRIPTION
40.Dx
41provides a complete build environment suitable for users to make
42full releases of the
43.Dx
44operating system.
45All of the tools necessary to build releases are available from the
46git repository in
47.Pa src/nrelease .
48A complete release (that is, a live CD) can actually be built with
49only a single command.
50This command is aptly named
51.Dq Li "make release" .
52.Pp
53This document does not cover source code management, quality
54assurance, or other aspects of the release engineering process.
55.Sh TARGETS
56The release Makefile
57.Pq Pa src/nrelease/Makefile
58defines a number of targets which are roughly modeled after the
59targets used for building the system.
60.Bl -tag -width ".Cm realquickrel"
61.It Cm help
62Offer some help.
63.It Cm release
64Builds world and kernel, installs them, adds packages and prepares the ISO
65image.
66.It Cm quickrel
67Same as
68.Cm release
69but uses the
70.Cm quickworld
71target (alias
72.Cm quick ) .
73.It Cm realquickrel
74Same as
75.Cm release
76but uses the
77.Cm realquickworld
78target (alias
79.Cm realquick ) .
80.It Cm clean
81Removes the ISO root directory and object files.
82.It Cm realclean
83Same as
84.Cm clean
85but also removes external packages.
86.El
87.Pp
88The
89.Cm quickrel
90and
91.Cm realquickrel
92targets will only work if a full
93.Cm buildworld
94and
95.Cm buildkernel
96have been done before.
97For a description of the corresponding build targets, see
98.Xr build 7 .
99.Pp
100A number of additional targets may be specified along with
101.Cm release ,
102.Cm quickrel ,
103or
104.Cm realquickrel
105to add additional features:
106.Bl -tag -width ".Cm realquickrel"
107.It Cm gui
108Adds
109.Xr Xorg 1
110along with some additional applications to the ISO (LiveDVD).
111.It Cm nopkgs
112Do not add any packages (for debugging purposes).
113This is equivalent to setting
114.Va DPORTS_PACKAGES
115empty.
116.El
117.Pp
118During the process of rolling a release a check is performed to find
119out if external packages to be put on the CD exist on your system.
120If they cannot be found, the release process will stop and give
121proper commands for downloading and setting up these packages.
122.Sh ENVIRONMENT
123.Bl -tag -width ".Va DPORTS_EXTRA_PACKAGES"
124.It Va DPORTS_PACKAGES
125List of packages to be added to the ISO.
126.It Va DPORTS_EXTRA_PACKAGES
127List of packages, in addition to
128.Va DPORTS_PACKAGES ,
129to be added to the ISO.
130.It Va DPORTS_PATH
131Location of the
132.Xr dports 7
133tree to be used for package building.
134.It Va GITURL_SRC
135The Git URL to the system source repository.
136.It Va GITURL_DPORTS
137The Git URL to the
138.Xr dports 7
139repository.
140.It Va IMGFILE
141The name of the image file (default is
142.Pa /usr/obj/release/dfly.img ) .
143.It Va IMGMNT
144The mount point for the image (default is
145.Pa /usr/obj/release/mnt ) .
146.It Va IMGSIZE
147The size of the IMG file (in units of 512-byte sector).
148The default size is determined from the actual content by leaving about
149600 MB free space.
150.It Va ISODIR
151Default prefix of
152.Va ISOFILE
153and
154.Va ISOROOT
155(default is
156.Pa /usr/obj/release ) .
157.It Va ISOFILE
158Name of the ISO image to generate (default is
159.Pa /usr/obj/release/dfly.iso ) .
160.It Va ISOROOT
161Location where the image contents are installed to before the ISO is prepared.
162.It Va KERNCONF
163Kernel configuration to use.
164.It Va LABEL
165The name of the
166.Xr disklabel64 5
167slice in the IMG file and is used to identify the installation USB device.
168The is also the volume ID of the ISO file.
169.It Va MAKE_JOBS
170The number of make jobs (default is the value of sysctl
171.Va hw.ncpu ) .
172.It Va WITHOUT_SRCS
173If set, this variable will prevent source code from being copied to
174the ISO image.
175.El
176.Sh FILES
177.Bl -tag -compact -width ".Pa src/nrelease/Makefile"
178.It Pa /etc/make.conf
179.It Pa src/Makefile
180.It Pa src/Makefile.inc1
181.It Pa src/nrelease/Makefile
182.El
183.Sh EXAMPLES
184The following sequence of commands is used to build a standard
185.Dx 2.0
186installation CD image (assuming that a local git repository is
187available, see
188.Xr development 7
189for how to get this):
190.Bd -literal -offset indent
191cd /usr/src
192git checkout -b rel2_0 crater/DragonFly_RELEASE_2_0
193cd nrelease
194make release
195.Ed
196.Pp
197After running these commands, the image will be available in the
198.Pa /usr/obj/release
199directory.
200.\".Pp
201.\"The steps required for engineering a release are documented in (CVS)
202.\".Pa doc/notes/release.txt
203.\"(how to branch the CVS tree etc.)
204.\"They were put in an out of the way place so normal developers would not
205.\"accidentally try to run the commands in question.
