People who are interested in porting software between open source platforms such as Linux and the members of the BSD family just gained a new tool: a cgroup filesystem for the BSDs. "CGrpFS is a tiny implementation of the GNU/Linux CGroup filesystem for BSD platforms. It takes the form of a FUSE filesystem and implements robust tracking of processes. Resource control, however, is not present; the different BSD platforms each provide different mechanisms for this, none of which are easily adapted to CGroups semantics. The process tracking alone is sufficient for the main user of CGrpFS, InitWare, a service manager derived from systemd." This effort should make it easier to port software from Linux to the members of the BSD family, especially packages which usually rely on systemd.
