Ceph install overwrites python3.7/site-packages/easy-install.pth

Hi I noted, when compile Ceph from source and install, the "make install" overwrites the /usr/local/lib/python3.7/site-packages/easy-install.pth. Before install Ceph, /usr/local/lib/python3.7/site-packages/easy-install.pth: import sys; sys.__plen = len(sys.path) import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new) After install Ceph, /usr/local/lib/python3.7/site-packages/easy-install.pth: ./ceph_volume-1.0.0-py3.7.egg ./ceph_volume_zfs-0.1.0-py3.7.egg ./ceph-1.0.0-py3.7.egg The source is git master (v15.1.0). Are you sure this overwrite is right? Did you all mean to append ceph stuff? Btw, I'm not a Python programmer, but as a sys admin it's quite scaring my previous content gone. Regards Sagara
