DESCRIPTION:Recently\, atomic updates via image based systems have become m
 ore relevant for\nservers and desktops\, as they allow predictable managem
 ent of large fleets. In the\nembedded Linux space\, this approach has been
  the default for many years and\nproven updaters exist already.\n\nIn this
  talk\, we will delve into RAUC and look at how its design and features\nh
 ave been driven by the requirements for robust\, atomic updates.\nThe pres
 entation will introduce the fundamental concepts surrounding A/B fallback\
 nand update signing in the context of embedded Linux updates.\nWe will the
 n explore the commonalities and differences between RAUC and systemd's\nsy
 supdate.\n\nThe discussion will progress to cover RAUC's bundle-based upda
 te system\, which\nallows for comprehensive system updates without the nee
 d for local storage\,\nthanks to HTTP streaming. Additionally\, we will de
 monstrate how adaptive updates\nminimize download sizes without necessitat
 ing version-specific patch management.
