[$] 14 years of systemd

It is a standard practice to use milestones to reflect on theachievements of a project, such as the anniversary of its firstrelease or first commit. Usually, these are observed at five andtenyear increments; the tenth anniversary of the 1.0 release, or 25years since from the first public announcement, etc. LennartPoettering, however, took a different approach at FOSDEM2025 with a keynotecommemorating 14 years of systemd,and a brief look ahead at his goals and systemd's challenges for the future.
