cfsd - cryptographic file system daemon
cfsd is the user-level daemon for the Cryptographic File System (CFS).
It is essentially an RPC server for the NFS protocol augmented with the
CFS_ADMIN protocol. It listens on the CFS port (ordinarily port 3049)
on the localhost interface.
The main function of cfsd is to manage the keys for currently attached
encrypted directories, presenting them in clear form under the CFS
mount point (typically "/crypt").
cfsd should ordinarily be invoked at boot time from /etc/rc (or
/etc/rc.local). The rc file should also start mountd(8) daemon with
least one file system exported to localhost; note that cfsd itself does
not handle the mount protocol. Once a mountd is running, the mount(8)
command should be invoked to mount the exported file system from the
localhost interface with port=3049.

cfsd is single threaded, which means it doesn’t handle lots of
simultanious operations very well. In particular, it is not possible
to recursively attach encrypted directories, since that would lead to a
