Functions

func ExpandSlice

func ExpandSlice(slice string) (string, error)

systemd represents slice hierarchy using `-`, so we need to follow suit when generating the path of slice. Essentially, test-a-b.slice becomes /test.slice/test-a.slice/test-a-b.slice.

func NewSystemdCgroupsManager

func NewSystemdCgroupsManager() (func(config *configs.Cgroup, paths map[string]string) cgroups.Manager, error)

func UseSystemd

func UseSystemd() bool
