Abstract

Mandriva Linux exists in several architectures. All the packages are not always present in all the available architectures. Right now the two main architectures are i586 and x86_64. PPC is also still maintained by the community.

The script checks all the available source packages included in the version and checks for all the binaries if they are synchronized or not.

For 'main' media:

A = Total missing x86_64 main: 92 (the packages in i586 but not in x86_64) B = Total extra x86_64 main: 21 (the packages in x86_64 but not in i586) C = Total unsynchro x86_64 main: 67 (the packages with different version in x86_64 and i586)

For 'contrib' media:

D = Total missing x86_64 contrib: 1347 E = Total extra x86_64 contrib: 47 F = Total unsynchro x86_64 contrib: 286

Then a level of unsynchronisation is calculated (2*A + 2*B + C + 2*D + 2*E + F)/4*(total main i586 packages + total contrib i586 packages).

20060316174720 /mnt/BIG/dis/2006.0/ x86_64 unsynchronization level: 0.0732338611449452

Likely this number is not really meaningful by itself, although it means that the differences are about 7% (ponderated) between i586 and x86_64. What is more important is to make this number as low as possible, so to log it over time and see if it grows (bad) or diminish (good).
