Segue from systemd/journald into:

“Super daemon for all daemons”

    Replaced things like sysvinit, rc.d, and even inetd

Lennart Poettering and Kay Sievers

Systemd (PID1)

    Configured using only text files

        .service

        .device

        .swap

        .timer (.service file of the same time must exist)

            ‘Transient timers can be created’

            https://wiki.archlinux.org/index.php/Systemd/Timers

/etc/systemd/system/foo.timer

[Unit]
Description=Run foo weekly and on boot

[Timer]
OnBootSec=15min
OnUnitActiveSec=1w

[Install]
WantedBy=timers.target

Logs are in binary format

Cgroups - control groups

    Isolates resource usage (CPU, memory, disk I/O, network, etc) of processes

    Bound by the same criteria

    Used a lot of places (hadoop, k8s, docker, LXC)
