Poettering: The Biggest Myths
Poettering: The Biggest Myths
Lennart Poettering decided to refute a few
systemd myths on his blog, where "a few" means "30". "There's
certainly some truth in that. systemd's sources do not contain a single
line of code originating from original UNIX. However, we drive inspiration
from UNIX, and thus there's a ton of UNIX in systemd. For example, the UNIX
idea of 'everything is a file' finds reflection in that in systemd all
services are exposed at runtime in a kernel file system, the
cgroupfs. Then, one of the original features of UNIX was multi-seat
support, based on built-in terminal support. Text terminals are hardly the
state of the art how you interface with your computer these days
however. With systemd we brought native multi-seat support back, but this
time with full support for today's hardware, covering graphics, mice,
audio, webcams and more, and all that fully automatic, hotplug-capable and
without configuration.
