 %description
-LXCFS is a simple userspace filesystem designed to work around some
-current limitations of the Linux kernel.
+LXCFS is a small FUSE filesystem written with the intention of making
+Linux containers feel more like a virtual machine. It started as a
+side-project of LXC but is usable by any runtime.
 
-Specifically, it's providing two main things
-
-- A set of files which can be bind-mounted over their /proc originals
-  to provide CGroup-aware values.
-
-- A cgroupfs-like tree which is container aware.
-
-The code is pretty simple, written in C using libfuse.
-
-The main driver for this work was the need to run systemd based
-containers as a regular unprivileged user while still allowing systemd
-inside the container to interact with cgroups.
-
-Now with the introduction of the cgroup namespace in the Linux kernel,
-that part is no longer necessary on recent kernels and focus is now on
-making containers feel more like a real independent system through the
-proc masking feature.
+LXCFS will take care that the information provided by crucial files in
+procfs are container aware such that the values displayed (e.g. in
+/proc/uptime) really reflect how long the container is running and not
+how long the host is running.
