[$] 14 years of systemd

It is a standard practice to use milestones to reflect on the
achievements of a project, such as the anniversary of its first
release or first commit. Usually, these are observed at five and
ten‑year increments; the tenth anniversary of the 1.0 release, or 25
years since from the first public announcement, etc. Lennart
Poettering, however, took a different approach at FOSDEM 2025 with a keynote
commemorating 14 years of systemd,
and a brief look ahead at his goals and systemd's challenges for the future.
