The value of the 5 fields may be "unknown" in case the function was unable to recognize on which distribution it is running.
|

| 175 |
|
|---|
| 176 | 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.
|
|---|
| 177 | 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.
|
|---|
| 178 | And "fc" is the extension generated for all Fedora packages (Version will be added by pb).
|
|---|
| 179 |
|
|---|
| 180 | 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.
