In 2008 libcgroup was created to simplify how users interact with and manage cgroups. At the time, only cgroups v1 existed, the libcgroup source was hosted in a subversion repository on Sourceforce, and System V still ruled the universe. Fast forward to today and the landscape is changing quickly. To pave the way for cgroups v2 support in libcgroup, we have added unit tests, functional tests, continuous integration, code coverage, and more.
