Sage Weil e3b4ba99cc filestore: create snap_0 on mkfs 
If we create a new filestore, apply one transaction, and then crash, we
want to make sure roll back to a consistent reference point--empty.  The
simplest solution is to create that snap_0 during mkfs.  This avoids
strangeness like

Ceph - a scalable distributed storage system
-----------------------------------------

Please see http://ceph.newdream.net/ for current info.

----

To build the server daemons, and FUSE client,

$ ./autogen.sh
$ ./configure
$ make

(Note that the FUSE client will only be built if libfuse is present.)

----

A quick summary of binaries that will be built in src/

daemons:
 ceph-mon -- monitor daemon.  handles cluster state and configuration
         information.
 ceph-osd -- storage daemon.  stores objects on a given block device.
 ceph-mds -- metadata daemon.  handles file system namespace.
 ceph-fuse -- fuse client.

tools:
 ceph -- send management commands to the monitor cluster.
 rados -- interact with the object store
 rbd -- manipulate rados block device images
 monmaptool -- create/edit mon map
 osdmaptool -- create/edit osd map 
 crushtool -- create/edit crush map

scripts:
 mkcephfs -- cluster mkfs tool
 init-ceph -- init.d start/stop script
