DESCRIPTION:How do we provide platform engineers and security architects wi
 th the same immutability and integrity for the operating system (OS) that 
 they expect from containers? While OSTree pioneered transactional deployme
 nts\, the ecosystem has shifted toward OCI images and sealed\, hardware-ro
 oted attestation\, leaving a gap for a standardized\, verifiable OS delive
 ry path.\n\nThis talk introduces a shift in image-mode Linux\, aligning th
 e OS directly with the OCI model using bootc and composefs. By consuming O
 CI images and materializing them through composefs\, we create a bootable\
 , verifiable filesystem with strong lifecycle and update guarantees.\n\nWe
  compare this approach with traditional OSTree methods\, examining layerin
 g\, updates\, and operational trade-offs. We will demonstrate deploying a 
 composefs-backed system on Fedora 44.\n\nAfter this talk\, attendees will 
 be ready to build\, verify\, and deploy OCI-native operating systems with 
 production-grade integrity.

DESCRIPTION:In this meetup\, we will focus on the topic of LLMs/GenAI and F
 OSS: there's obviously a wide spectrum of opinion here\, from banning it t
 o 100% vibecoding. The goal of this meetup is especially to focus in on th
 ose who need/want to LLMs safely and responsibly for "important" software.
  What are the shared best practices\, tools and procedures? What can we do
  to use these tools to address prior problems around things like supply ch
 ain security?\n\nThe submitter of this workshop has a lot of of experience
  and opinions\, but is looking to have a realistic in-person discussion wh
 ere different tools and experiences are presented and attendees can learn 
 from each other.
