.TH "MKIMAGE-PROFILES" "9" "October 2021" "mkimage-profiles @VERSION@" "ALT"
|
|
.SH "NAME"
|
|
mkimage-profiles \- ALT distribution family metaprofile
|
|
.SH "SYNOPSIS"
|
|
.B make
|
|
.IR "" [ options ]
|
|
.I "" [ <goal> ... ]
|
|
.SH "DESCRIPTION"
|
|
.BR mkimage-profiles
|
|
builds operating environment images based on ALT package repositories.
|
|
|
|
Run
|
|
.BR make\ help
|
|
to obtain list of available goals.
|
|
.SH "PREREQUISITES"
|
|
mkimage-profiles only needs
|
|
.BR make(1)
|
|
and
|
|
.BR rsync(1)
|
|
to generate the build profile;
|
|
.BR mkimage
|
|
is used to actually run the build (which involves
|
|
.BR hasher(7)
|
|
quite a few times).
|
|
|
|
.BR git(1)
|
|
will be used if available so that the generated profile is an annotated
|
|
git repository;
|
|
.BR graphviz(1)
|
|
can be used to obtain build dependency graphs.
|
|
.SH "RATIONALE"
|
|
Long time ago when Linux distribution images were worked upon by hand
|
|
there was little need for generalization and sharing the common base.
|
|
|
|
Building several "generic" ALT{, Linux} distros in a team and maintaining
|
|
their educational flavours at the same time proved the need to be able
|
|
to describe what's common and what's different in a way that doesn't
|
|
resemble more or less complete forks.
|
|
|
|
Enter mkimage-profiles: choose what's closest to your dream image
|
|
and add what's missing, or roll on your own using the rich library
|
|
of existing parts and bits.
|
|
.SH "REQUIREMENTS"
|
|
The next-generation image build system for ALT must:
|
|
.TP
|
|
1.
|
|
provide reasonable means to describe common/differing aspects within
|
|
image families;
|
|
.TP
|
|
2.
|
|
ensure reproducible build results;
|
|
.TP
|
|
3.
|
|
support distribution family maintenance workflows
|
|
observed in the wild (e.g., with
|
|
.BR mkimage-profiles-desktop
|
|
or earlier);
|
|
.TP
|
|
4.
|
|
help out with diagnosing build problems.
|
|
.SH "ARCHITECTURE"
|
|
.BR mkimage-profiles
|
|
implements four steps to achieve the above goals:
|
|
.TP
|
|
1.
|
|
initialize the off-tree mkimage profile (BUILDDIR);
|
|
.TP
|
|
2.
|
|
build up distribution's configuration there;
|
|
.TP
|
|
3.
|
|
copy over the needed subprofiles/features/lists/groups;
|
|
.TP
|
|
4.
|
|
build the ISO/VE/VM image.
|
|
.PP
|
|
This results in a compact "as-needed" style per-image profile that can
|
|
be actually studied in a short amount of time and might get included
|
|
into the generated image as a tarball for better reproducibility.
|
|
.SH "EXAMPLES"
|
|
.BR make\ syslinux.iso
|
|
should result in a minimal bootable ISO image.
|
|
|

|
|
First and foremost:
|
|
.BR /usr/share/mkimage-profiles/QUICKSTART
|
|
|
|
Please refer to
|
|
.BR README
|
|
files in the tree starting with the toplevel one for more
|
|
information; these can be assembled into a handbook using
|
|
.BR asciidoc(1)
|
|
(available at
|
|
.BR https://nightly.altlinux.org/docs/
|
|
as weekly HTML/PDF updates).
|
|
|
|
Specific topics are covered within
|
|
.BR doc/
|
|
subdirectory; e.g.
|
|
.BR make
|
|
options are described in
|
|
.BR doc/params.txt
|
|
file.
