28.Dt RELEASE 7 29.Os 30.Sh NAME 31.Nm release 32.Nd "release building infrastructure" 33.Sh DESCRIPTION 34.Fx 35provides a complete build environment suitable for users to make 36full releases of the 37.Fx 38operating system. 39All of the tools necessary to build a release are available from the 40.Fx 41source code repository in 42.Pa src/release . 43A complete release can actually be built with only a single command, 44including the creation of ISO images suitable for burning to CD-ROM, 45memory stick images, and an FTP install directory. 46This command is aptly named 47.Dq Li "make release" . 48.Pp 49For some users, it may be desirable to provide an absolutely clean 50build environment, with no local modifications to the source tree or to 51.Xr make.conf 5 , 52and with clean checkouts of specific versions of the doc, src, and ports 53trees. 54For this purpose, a script 55.Pq Pa src/release/release.sh 56is provided to automate these checkouts and then execute 57.Dq Li "make release" 58in a clean 59.Xr chroot 8 . 60.Pp 61Before attempting to build a release, the user is expected to be 62familiar with the contents of 63.Xr build 7 , 64and should have experience upgrading systems from source. 65.Pp 66The release build process requires that 67.Pa /usr/obj 68be populated with the output of 69.Dq Li "make buildworld" 70and 71.Dq Li "make buildkernel" . 72This is necessary to provide the object files for the release or, when 73using 74.Pa release.sh , 75so that the object files for a complete system can be installed into a clean 76.Xr chroot 8 77environment. 78.Pp 79If the target release build is for a different architecture or machine type, 80the 81.Va TARGET 82and 83.Va TARGET_ARCH 84variables must be used. 85See the supported 86.Fa release.conf 87variables for more information. 88.Pp 89The release procedure on some architectures may also require that the 90.Xr md 4 91(memory disk) device driver be present in the kernel 92.Pq either by being compiled in or available as a module . 93.Pp 94This document does not cover source code management, quality 95assurance, or other aspects of the release engineering process. 96.Sh CLEAN RELEASE GENERATION 97Official releases of 98.Fx 99are produced in a totally clean environment to 100ensure consistency between the versions of the src, ports, and doc trees 101and to avoid contamination from the host system 102.Po such as local patches, changes 103to 104.Xr make.conf 5 , 105etc. 106.Pc . 107This is accomplished using the wrapper script 108.Pa src/release/release.sh . 109.Pp 110.Ic release.sh 111.Op Fl c Ar release.conf 112.Pp 113.Ic release.sh 114checks out the 115.Li src/ , 116.Li ports/ , 117and 118.Li doc/ 119trees to 120.Va CHROOTDIR , 121then calls 122.Dq Li "make buildworld" 123and 124.Dq Li "make installworld" 125to generate a 126.Xr chroot 8 127environment. 128Next, 129.Dq Li "make release" 130is run within the 131.Xr chroot 8 132environment and places the result in 133.Pa $CHROOTDIR/R . 134.Pp 135The optional 136.Fa release.conf 137configuration file supports the following variables: 138.Bl -tag -width Ev 139.It Va CHROOTDIR 140The directory within which the release will be built. 141.It Va CHROOT_MAKEENV 142Additional 143.Xr make 1 144arguments to pass through, which directly affect the 145tuning of the build chroot. 146.It Va SVNROOT 147The 148.Xr svn 1 149host used to check

All the others have one. 340.Bl -tag -width ".Cm packagesystem" 341.It Cm release 342Meta-target to build all release media and distributions applicable to this 343platform. 344.It Cm install 345Copy all produced release media to 346.Pa ${DESTDIR} . 347.It Cm cdrom 348Builds installation CD-ROM images. 349This may require the 350.Xr md 4 351(memory disk) device driver be present in the kernel 352(either by being compiled in or available as a module). 353This target produces files called 354.Pa disc1.iso 355and 356.Pa bootonly.iso 357as its output. 358.It Cm dvdrom 359Builds installation DVD-ROM images. 360This may require the 361.Xr md 4 362(memory disk) device driver be present in the kernel 363(either by being compiled in or available as a module). 364This target produces the 365.Pa dvd1.iso 366file as its output. 367.It Cm memstick 368Builds an installation memory stick image named 369.Pa memstick.img . 370Not applicable on all platforms. 371Requires that the 372.Xr md 4 373.Pq memory disk 374device driver be present in the kernel 375.Pq either by being compiled in or available as a module . 376.It Cm mini-memstick 377Similar to 378.Cm memstick , 379with the exception that the installation distribution sets 380are not included. 381.It Cm ftp 382Creates a directory named 383.Pa ftp 384containing the distribution files used in network installations 385and suitable for upload to an FTP mirror. 386.El 387.Pp 388Major subtargets called by targets above: 389.Bl -tag -width ".Cm packagesystem" 390.It Cm packagesystem 391Generates all the distribution archives 392.Pq base, kernel, ports, doc 393applicable on this platform. 394.It Cm system 395Builds a bootable installation system containing all the distribution files 396packaged by the 397.Cm packagesystem 398target, and suitable for imaging by the 399.Cm cdrom , 400.Cm dvdrom 401and 402.Cm memstick 403targets. 404.It Cm reldoc 405Builds the release documentation. 406This includes the release notes, 407hardware guide, and installation instructions. 408Other documentation, such as the Handbook, 409is built during the 410.Cm base.txz 411target invoked by 412.Cm packagesystem . 413.El 414.Sh

output of 421.Ic `uname -s`-`uname -r`-`uname -p` 422within the chroot. 423.It Ev WORLDDIR 424Location of a directory containing the src tree. 425By default, the directory 426above the one containing the makefile 427.Pq Pa src . 428.It Ev PORTSDIR 429Location of a directory containing the ports tree. 430By default, 431.Pa /usr/ports . 432If it is unset or cannot be found, ports will not be included in the release. 433.It Ev DOCDIR 434Location of a directory containing the doc tree. 435By default, 436.Pa /usr/doc . 437If it is unset or cannot be found, most documentation will not be included in 438the release; see 439.Ev NODOC 440below. 441.It Ev NOPORTS 442If defined, the Ports Collection will be omitted from the release. 443.It Ev NOSRC 444If set, do not include system source code in the release. 445.It Ev NODOC 446If defined, the XML-based documentation from the 447.Fx 448Documentation Project will not be built. 449However, the 450.Dq doc 451distribution will still be created with the minimal documentation set 452provided in 453.Pa src/share/doc . 454.It Ev TARGET 455The target hardware platform. 456This is analogous to the 457.Dq Nm uname Fl m 458output. 459This is necessary to cross-build some target architectures. 460For example, cross-building for PC98 machines requires 461.Ev TARGET_ARCH Ns = Ns Li i386 462and 463.Ev TARGET Ns = Ns Li pc98 . 464If not set, 465.Ev TARGET 466defaults to the current hardware platform. 467.It Ev TARGET_ARCH 468The target machine processor architecture. 469This is analogous to the 470.Dq Nm uname Fl p 471output. 472Set this to cross-build for a different architecture. 473If not set, 474.Ev TARGET_ARCH 475defaults to the current machine architecture, unless 476.Ev TARGET 477is also set, in which case it defaults to

| 299.El 300.Sh EMBEDDED BUILDS 301The following 302.Fa release.conf 303variables are relevant only to release builds for embedded systems: 304.Bl -tag -width Ev 305.It Va EMBEDDEDBUILD 306Set to a non-null value to enable functionality for embedded device 307release builds. 308.Pq This option is considered highly experimental. 309.Pp 310When set, 311.Va WITH_DVD 312is unset, and 313.Va NODOC 314is defined. 315Additionally, 316.Va XDEV 317and 318.Va XDEV_ARCH 319must also be defined. 320When the build environment is created, 321.Fa release.sh 322runs a separate build script located in an architecture-specific 323directory in 324.Pa src/release/${XDEV}/ . 325.It Va EMBEDDEDPORTS 326Set to the list of any ports that are required for the target device 327in the format of 328.Fa category/port . 329The 330.Fa devel/subversion 331port is built by default. 332.It Va CROCHETSRC 333Set to the source URL for the Crochet build tool. 334.It Va CROCHETBRANCH 335Set to the subversion branch from 336.Va ${CROCHETSRC} 337to use. 338Defaults to 339.Pa trunk . 340.It Va UBOOTSRC 341Set to the source URL of u-boot, if required. 342.It Va UBOOTBRANCH 343Set to the subversion branch from 344.Va ${UBOOTSRC} 345to use. 346Defaults to 347.Pa trunk . 348.It Va UBOOTDIR 349Set to the target directory within 350.Va ${CHROOTDIR} 351to check out 352.Va ${UBOOTSRC}/${UBOOTBRANCH} . 353.El 354.Sh MAKEFILE TARGETS 355The release makefile 356.Pq Pa src/release/Makefile 357is fairly abstruse. 358Most developers will only be concerned with the 359.Cm release 360and 361.Cm install 362targets. 363.\" XXX: Some sort of introduction to this list? All the others have one. 364.Bl -tag -width ".Cm packagesystem" 365.It Cm release 366Meta-target to build all release media and distributions applicable to this 367platform. 368.It Cm install 369Copy all produced release media to 370.Pa ${DESTDIR} . 371.It Cm cdrom 372Builds installation CD-ROM images. 373This may require the 374.Xr md 4 375(memory disk) device driver be present in the kernel 376(either by being compiled in or available as a module). 377This target produces files called 378.Pa disc1.iso 379and 380.Pa bootonly.iso 381as its output. 382.It Cm dvdrom 383Builds installation DVD-ROM images. 384This may require the 385.Xr md 4 386(memory disk) device driver be present in the kernel 387(either by being compiled in or available as a module). 388This target produces the 389.Pa dvd1.iso 390file as its output. 391.It Cm memstick 392Builds an installation memory stick image named 393.Pa memstick.img . 394Not applicable on all platforms. 395Requires that the 396.Xr md 4 397.Pq memory disk 398device driver be present in the kernel 399.Pq either by being compiled in or available as a module . 400.It Cm mini-memstick 401Similar to 402.Cm memstick , 403with the exception that the installation distribution sets 404are not included. 405.It Cm ftp 406Creates a directory named 407.Pa ftp 408containing the distribution files used in network installations 409and suitable for upload to an FTP mirror. 410.El 411.Pp 412Major subtargets called by targets above: 413.Bl -tag -width ".Cm packagesystem" 414.It Cm packagesystem 415Generates all the distribution archives 416.Pq base, kernel, ports, doc 417applicable on this platform. 418.It Cm system 419Builds a bootable installation system containing all the distribution files 420packaged by the 421.Cm packagesystem 422target, and suitable for imaging by the 423.Cm cdrom , 424.Cm dvdrom 425and 426.Cm memstick 427targets. 428.It Cm reldoc 429Builds the release documentation. 430This includes the release notes, 431hardware guide, and installation instructions. 432Other documentation, such as the Handbook, 433is built during the 434.Cm base.txz 435target invoked by 436.Cm packagesystem . 437.El 438.Sh ENVIRONMENT 439Optional variables: 440.Bl -tag -width ".Ev TARGET_ARCH" 441.It Ev OSRELEASE 442Optional base name for generated media images 443.Pq e.g., FreeBSD-9.0-RC2-amd64 . 444Defaults to the output of 445.Ic `uname -s`-`uname -r`-`uname -p` 446within the chroot. 447.It Ev WORLDDIR 448Location of a directory containing the src tree. 449By default, the directory 450above the one containing the makefile 451.Pq Pa src . 452.It Ev PORTSDIR 453Location of a directory containing the ports tree. 454By default, 455.Pa /usr/ports . 456If it is unset or cannot be found, ports will not be included in the release. 457.It Ev DOCDIR 458Location of a directory containing the doc tree. 459By default, 460.Pa /usr/doc . 461If it is unset or cannot be found, most documentation will not be included in 462the release; see 463.Ev NODOC 464below. 465.It Ev NOPORTS 466If defined, the Ports Collection will be omitted from the release. 467.It Ev NOSRC 468If set, do not include system source code in the release. 469.It Ev NODOC 470If defined, the XML-based documentation from the 471.Fx 472Documentation Project will not be built. 473However, the 474.Dq doc 475distribution will still be created with the minimal documentation set 476provided in 477.Pa src/share/doc . 478.It Ev TARGET 479The target hardware platform. 480This is analogous to the 481.Dq Nm uname Fl m 482output. 483This is necessary to cross-build some target architectures. 484For example, cross-building for PC98 machines requires 485.Ev TARGET_ARCH Ns = Ns Li i386 486and 487.Ev TARGET Ns = Ns Li pc98 . 488If not set, 489.Ev TARGET 490defaults to the current hardware platform. 491.It Ev TARGET_ARCH 492The target machine processor architecture. 493This is analogous to the 494.Dq Nm uname Fl p 495output. 496Set this to cross-build for a different architecture. 497If not set, 498.Ev TARGET_ARCH 499defaults to the current machine architecture, unless 500.Ev TARGET 501is also set, in which case it defaults to the appropriate 502value for that platform. 503Typically, one only needs to set 504.Ev TARGET . 505.El 506.Sh FILES 507.Bl -tag -compact -width Pa 508.It Pa /usr/doc/Makefile 509.It Pa
