xfs 6.8.2-10 (sparc binary) in ubuntu hoary

X font server
 xfs is a daemon that listens on a network port and serves X fonts to X
 servers (and thus to X clients). All X servers have the ability to serve
 locally installed fonts for themselves, but xfs makes it possible to offload
 that job from the X server, and/or have a central repository of fonts on a
 networked machine running xfs so that all the machines running X servers on a
 network do not require their own set of fonts. xfs may also be invoked by
 users to, for instance, make available X fonts in user accounts that are not
 available to the X server or to an already running system xfs.
