Poettering: systemd for Administrators, Part XVIII (controllers)

The eighteenth
of Lennart Poettering's "systemd for Administrators" series
covers an interesting newish feature: integrated support for control group
resource controllers. "When thinking about service management for
systemd, we quickly realized that resource management must be core
functionality of it. In a modern world -- regardless if server or embedded
-- controlling CPU, Memory, and IO resources of the various services cannot
be an afterthought, but must be built-in as first-class service
settings. And it must be per-service and not per-process as the traditional
nice values or POSIX Resource Limits were."

management of the journal.
