Public bug reported: The version of libseccomp2 in bionic does not know about the openat2 syscall.
In my particular usecase, I was trying to run podman/buildah in an nspawn container, using fuse-overlayfs. This leads to peculiar failure modes as described in this issue: https://github.com/containers/fuse-overlayfs/issues/220 This could well cause other problems, previously issues like that have affected snapd, etc. Backporting the master branch of libseccomp fixed this for me, but for an SRU a cherrypick of https://github.com/seccomp/libseccomp/commit/b3206ad5645dceda89538ea8acc984078ab697ab might be sufficient...
