%description
LXCFS is a simple userspace filesystem designed to work around some
current limitations of the Linux kernel.

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 and glib.

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.

%description -n pam-pam_cgfs
When a user logs in, this pam module will create cgroups which the
user may administer, either for all controllers or for any controllers
listed on the command line.

# The lxcfs executable requires liblxcfs.so be installed. It calls dlopen() to
# dynamically reload the shared library on upgrade. This is important. Do *not*
# split into a separate package and do not turn this into a versioned shared
# library! (This shared library allows lxcfs to be updated without having to
# restart it which is good when you have important system containers running!)
