Currently, we manually put proprietary binaries in /opt/amarisoft on servers which run the "ors-amarisoft" software release. We are not allowed to publish these binaries, so to automatically upgrade these binaries a private key will be generated locally on each machine and binaries will be encrypted and uploaded to shacache.

See https://www.erp5.com/project_section/vifib/forum/Howto-handle-proprietary-SR-in-SlapOS-37cP01sbVm for more details
