Yast2 CA Management store keys in "/var/lib/CAM".

The string "/var/lib/CAM" is used in :
/usr/lib/perl5/vendor_perl/5.18.2/x86_64-linux-thread-multi/auto/CaMgm/CaMgm.so

/usr/share/YaST2/clients/ca_mgm_proposal.rb
/usr/share/YaST2/include/ca-management/crlExport.rb
/usr/share/YaST2/modules/CaMgm.rb
/usr/share/YaST2/modules/YaPI/CaManagement.pm
/usr/share/YaST2/modules/YaST/caUtils.pm

Forgetting the first file (CaMgm.so), which is the best place to change the behavior of the software, and store certificates to an other folder.

Any help is welcome.
