Add an XSL stylesheet for listing packages in LFS. Those are
not listed anywhere else, but they are considered dependencies of
everything, so should never be erased.
Now gen_pkf_book.sh depends on trackfile. This can be passed
as an argument, but to ease calling it standalone, we need to
set the default to the actual file used.
With the new xsl/dependencies.xsl, the full dependency list is generated.
We compare the version and installed version gotten from packages.xml
using xsl/get_version.xsl and only install if the installed version is
lower than the available version. Since the installed version returned
by get_version.xsl for a non installed package is 0, that version is
always lower than the available version and the package is installed.
Note that if a package does not exist, both versions are empty, and
they compare as equal with our method. So they are never installed...
Get them in gen_pkg_book, and pass them to sripts.xsl
use them in scripts.xsl. We set them at the beginning of
of the scriptlet, so that it is easy to modify them.
- Even if only required or recommended deps only are requested and built,
account for optional deps to build the pacakge order
- build "runtime" deps after the pacakge dependening on them, but before
any other package
- using the "first" role in the book, implement pass1 pacakges when there
are circular dependencies
- Documentation has still to be written
- There must be bugs, thank you for testing...
