ceph-deploy fails when installed from package
ceph-deploy fails when installed from package

the list of path added by ceph-deploy does not cover all the deployment scenarios. In particular, when installed from a package it will end up in /usr/lib/python2.7/dist-packages/ceph_deploy . The error message is removed : the from will fail if it does not find the module.
