This fixes an issue only affecting users of the Checkmk 2.5 beta.

As of Checkmk version 2.5, all special agents and active checks require the following environment variables to be set.

PASSWORD_STORE_SECRET_FILE="${OMD_ROOT}/etc/password_store.secret"
SERVER_SIDE_PROGRAM_STORAGE_PATH="${OMD_ROOT}/var/check_mk/server_side_program_storage"
SERVER_SIDE_PROGRAM_CRASHES_PATH="${OMD_ROOT}/var/check_mk/crashes"

Previously, the execution of a special agent or an active check could result in the following error:

Environment variable PASSWORD_STORE_SECRET_FILE is not set

This has been fixed.
