|

| 64 | This function returns a list of 7 parameters indicating the distribution name, version, family, type of build system, suffix of packages, update command line and architecture of the underlying Linux distribution. The value of the 7 fields may be "unknown" in case the function was unable to recognize on which distribution it is running.
|
|---|
| 65 |
|
|---|
| 66 | As an example, Ubuntu and Debian are in the same "du" family. As well as RedHat, RHEL, CentOS, fedora are on the same "rh" family.
|
|---|
| 67 | 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.
|
|---|
| 68 | And "fc" is the extension generated for all Fedora packages (Version will be added by pb).
|
|---|
| 69 |
|
|---|
| 70 | When 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.
