 # ceph-patch
 Patches for cephadm managed Ceph installations
+
+Specifically the patch for ceph-volume which allows usage of "removable" SAS
+devices, which many controllers utilize to indicate a hot-pluggable slot. You
+can find this @ ceph/ceph#49954 .
+
+**Please do not use this image verbatim!** This works for me, and I trust my
+build of this, but I would advise you fork this and create your own package.
