  • Introduction of a new hash $pbos to manage all os related info through a single data structure. All functions reviewed accordingly. Externally transparent, hopefully, but much cleaner code as a consequence. VM/VE/RM remains to be tested.

    80 This function returns a list of 8 parameters indicating the distribution name, version, family, type of build system, suffix of packages, update command line, installation command line and architecture of the underlying Linux distribution. The value of the 8 fields may be "unknown" in case the function was unable to recognize on which distribution it is running.
     78This function returns a hash of parameters indicating the distribution name, version, family, type of build system, suffix of packages, update command line, installation command line and architecture of the underlying Linux distribution. The value of the fields may be "unknown" in case the function was unable to recognize on which distribution it is running.

    8280As an example, Ubuntu and Debian are in the same "du" family. As well as RedHat, RHEL, CentOS, fedora are on the same "rh" family.
    83 Mandriva, Open SuSE and Fedora have all the same "rpm" type of build system. Ubuntu ad Debian have the same "deb" type of build system.
     81Mandriva, Open SuSE and Fedora have all the same "rpm" type of build system. Ubuntu and Debian have the same "deb" type of build system.
    8482And "fc" is the extension generated for all Fedora packages (Version will be added by pb).
    85 All these information are stored in an external configuration file typically at /etc/pb/pb.conf

    8785When passing the distribution name and version as parameters, the B<pb_distro_init> function returns the parameter of that distribution instead of the underlying one.
