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.
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.
