Maybe it needs to be accepted to become public, anyway:
Containers are by far the biggest use case for overlayfs.
Yet, there seems to be very little cross talk between overlayfs and
containers mailing lists.
This talk is going to present some opt-in overlayfs features that were
added in recent years (redirect_dir, index, nfs_export, xino,
metacopy).
Most of those features have not been enabled by most container
runtimes, because of various reasons:
* Requires more development in userspace (image migration)
* Unrelated runtime bugs (mount leaks)
* Mismatch for containers needs
* Lack of promotion
This talk is about giving the opportunity to container runtime
developers to better understand what they may get from overlayfs.
This talk is not about containers wish list from overlayfs, because
userns overlayfs mount needs 45 minutes on its own...
Thanks,
Amir.
