 Progress from last report:
 ==========================
 
 Most important change:
- -	All test run to completion for the current selection of 
+  -	A port is submitted: net/ceph-devel.
-	tools. This is only the case for "My Fork" repository. Some of the 
-	commits need to be pulled into the HEAD
- -	As of now Cmake is the only way of building Ceph
-    - And testing would be best done thru ctest.
- -	Reworked threading/polling code for the simple socket code.
-	Now uses a selfpipe, instead of using an odd shutdown() signaling 
-	Linux feature.
- -	Modified the EventKqueue code to work around the "feature" that 
-	starting threads destroys the the kqueue handles. 
- -  ceph-disk should now be able to support FileStore on a ZFS disk.
-	The main reason that it needs to be ZFS is for xattribute: Size and number.
 
+Other improvements:
+
+	* A new ceph-devel update will be submitted in April
+
+  -	Ceph-Fuse works, allowing to mount a CephFS on a FreeBSD system and do
+	some work on it. 
+  -	Ceph-disk prepare and activate work for FileStore on ZFS, allowing 
+	easy creation of OSDs.
+  -	RBD is actually buildable and can be used to manage RADOS BLOCK 
+	DEVICEs.
+  -	Most of the awkward dependencies on Linux-isms are deleted only 
+	/bin/bash is there to stay.
+
+Getting the FreeBSD work on Ceph:
+=================================
+
+	pkg install net/ceph-devel

+Or:
+	cd "place to work on this"
+	git clone https://github.com/wjwithagen/ceph.git
+	cd ceph
+	git checkout wip.FreeBSD

+=========================

+ - KRBD
+	 Kernel Rados Block Devices is implemented in the Linux kernel
+	 And perhaps ggated could be used as a template since it does some of

+	 counterpart.
+ - BlueStore.
+	 FreeBSD and Linux have different AIO API, and that needs to be made 
+	 compatible Next to that is there discussion in FreeBSD about 
+	 aio_cancel not working for all devicetypes
+ - CephFS as native filesystem
+	 (Ceph-fuse does work.)
+	 Cython tries to access an internal field in dirent which does not
