2. OVERVIEW OF THE SYSTEM:
|
||||
|
||||
For now, package management is only available for LFS. I plan to
|
||||
upgrade BLFS tools, but nothing usable right now. The other flavours of
|
||||
LFS do not seem very active, so there is no point in updating jhalfs
|
||||
for them.
|
||||
The first thing to do is to modify the install instructions of the
|
||||
chapter 6, 7 and 8 of the book so that the installed files end up in a
|
||||
directory other than `/'. We choose to call this directory by the name
|
||||
of the executed script, and to put the path to this directory in the
|
||||
PKG_DEST variable which is made available to the scriplets.
|
||||
Almost all the packages have a way to redirect the destination of
|
||||
the files they install at the `make install' stage with the variable
|
||||
DESTDIR. Furthermore, the authors of the book have been kind enough to
|
||||
flag the installation instructions with `remap=install'. This allows an
|
||||
xsl stylesheet to find those instructions. Then, places where `make '
|
||||
occurs (make followed by a space) are replaced by `make DESTDIR=$PKG_DEST '.
|
||||
Places where the book instructions move files into their destination
|
||||
are harder to deal with: it is possible to change all occurences of ` /' or
|
||||
`>/' (beginning of absolute paths) to `$PKG_DEST', but you end up moving
|
||||
upgrade BLFS tools, but nothing usable right now. I have not attempted
|
||||
to adapt this tool for the other flavours of LFS.
|
||||
This system performs basically a "DESTDIR install" for all pages
|
||||
in chapter 6, 7 and 8 of the book. The name of the DESTDIR directory is the
|
||||
same as the one of the executed script. The path to this directory is
|
||||
available to the scriplets through the PKG_DEST variable.
|
||||
The XSL stylesheet used for generating the scriptlets, automatically
|
||||
adds DESTDIR install instructions when "package management" is selected.
|
||||
Also all the paths beginning with " /" or ">/" (absolute paths) are prepended
|
||||
with $PKG_DEST. This has the default that you might want to move
|
||||
files to non existent directories. There is no simple way to automatically
|
||||
create those directories, because you have sometimes to use the full path
|
||||
(instructions of the form `cp file dir') and sometimes only the dirname
|
||||
(instructions of the form `cp file1 file2'). So I am conservative and
|
||||
create a reasonable subset of the FHS hierarchy into the destination
|
||||
directory. Empty directories should then be removed before packing the
|
||||
(instructions of the form `cp file1 file2'). So the XSL stylesheet
|
||||
creates a reasonable subset of the FHS hierarchy into the destination
|
||||
directory. Empty directories are then removed before packing the
|
||||
binary package.
|
||||
Supposing now that the scriptlets have been adequately modified, the
|
||||
package manager installation instructions have to be added at the end of
|
||||
chapter 5 and chapter 6. Furthermore, the administrative files and
|
||||
directories have to be created during the `Creating Directories' and
|
||||
`Creating Essential Files' stage. For all this, the user has to supply a
|
||||
file in docbook format, with the necessary instructions and enough
|
||||
information to download the tarball. A template is provided in the pkgmngt
|
||||
subdirectory.
|
||||
In order to use the package manager, it has to be installed at the end of
|
||||
chapter 5 (temporary installation in /tools) and chapter 6 (final install).
|
||||
Furthermore, the administrative files and directories have to be created
|
||||
during the `Creating Directories' and `Creating Essential Files' stages.
|
||||
For all this, the user has to supply a file in docbook XML format, with
|
||||
the necessary instructions and enough information to download the tarball.
|
||||
This file should reside in the `pkgmngt' directory and be named
|
||||
`packageManager.xml'. A template named `packageManager.xml.template' is
|
||||
provided in the `pkgmngt' subdirectory. There are also two XML files for
|
||||
dpkg and pacman, respectively `packageManager.xml.dpkg' and
|
||||
`packageManager.xml.pacman', that you can copy to `packageManager.xml'.
|
||||
They are not updated often, so the versions used can be rather old.
|
||||
The last thing to do is to tell how to use the package manager. When
|
||||
the binary package is ready, the scriptlets call a shell function named
|
||||
`packInstall', which should pack the binary package and install it on the
|
||||
system. Note that nothing has been done to manage configuration files,
|
||||
which are ususally treated specially by package managers. Depending on
|
||||
which are ususally treated specially by package managers: depending on
|
||||
the book layout, it is sometimes possible to create those files afterwards,
|
||||
and sometimes not, which means that you have to check them after each
|
||||
upgrade. The user has to provide his own function. A template is provided
|
||||
in the pkgmngt subdirectory.
|
||||
|
||||
3. DETAILED INSTRUCTIONS:
|
||||
|
||||
Before beginning, you should know which package manager you want, where
|
||||
to get the sources, and how to use it for:
|
||||
a) Making a package from a directory tree. Usually, there is some control
|
||||
file containing the version, pacakager, build system (32 or 64 bits at
|
||||
least) or other more or less usefull but mandatory bits of information
|
||||
which you should understand.
|
||||
b) Unpack the package.
|
||||
|
||||
Second, you ought to have a basic knowledge of bash scripting and
|
||||
docbook-xml writing, because you have to write a bash function for packing
|
||||
and unpacking the package, and a set of instructions to install the PM.
|
||||
|
||||
upgrade. The user has to write his own `packInstall' function. The shell
|
||||
function should be defined in a file named `packInstall.sh', residing in
|
||||
the `pkgmngt' directory. A template is provided, as well as two example
|
||||
scripts for dpkg and pacman.
