+#!/usr/bin/python3
+'''
+Helper to mount ceph-fuse from /etc/fstab. To use, add an entry
+like:
+
+DEVICE PATH TYPE OPTIONS
+none /mnt/ceph fuse.ceph ceph.id=admin,_netdev,defaults 0 0
+none /mnt/ceph fuse.ceph ceph.name=client.admin,_netdev,defaults 0 0
+none /mnt/ceph fuse.ceph ceph.id=myuser,ceph.conf=/etc/ceph/foo.conf,_netdev,defaults 0 0
+
+ceph-fuse options are specified in the fs_mntops(4) column and must begin
+with 'ceph.' prefix. This way ceph related fs options will be passed to
+ceph-fuse and others will be ignored by ceph-fuse.
+
+The first two examples above specify that ceph-fuse will authenticate
+as client.admin. The third example specify that ceph-fuse will authenticate as
+client.myuser and also sets 'conf' option to '/etc/ceph/foo.conf' via ceph-fuse
+command line. Any valid ceph-fuse options can be passed this way.
+
+NOTE:
+Old format is also supported
+
+DEVICE PATH TYPE OPTIONS
+id=admin /mnt/ceph fuse.ceph defaults 0 0
+id=myuser,conf=/etc/ceph/foo.conf /mnt/ceph fuse.ceph defaults 0 0
