The Containers and Checkpoint/Restore micro-conference focuses on both userspace and kernel related work. The micro-conference targets the wider container ecosystem ideally with participants from all major container runtimes as well as init system developers.

The microconference will be discussing recent advancements in container technologies with some of the usual candidates being:

• CGroupV2 feature parity with CGroupV1
• Emulation of various files and system calls through FUSE and/or Seccomp
• Dealing with the eBPF-ification of the world
• Making user namespaces more accessible
• VFS idmap improvements

On the checkpoint/restore front, some of the potential topics include:

• Restoring FUSE services
• Handling GPUs
• Dealing with restartable sequences

And quite likely a variety of other container and checkpoint/restore topics as things evolve between now and the event.

Past editions of this micro-conference have been the source of many developments in the Linux kernel, including:

• PIDfds
• VFS idmap
• FUSE in user namespace
• Unprivileged overlayfs
• Time namespace
• A variety of CRIU features and checkpoint/restore kernel interfaces with the latest among them being
  • Unpriviledged checkpoint/restore
  • Support of rseq(2) checkpointing
