@AkihiroSuda k3s-io/k3s-root#29 has been merged and I'm tagging a new release with your addition - can you update your PR to include k3s-root bump to v0.7.1? |
Ubuntu and Debian kernels support mounting real overlayfs inside userns, but the vanilla kernel still does not allow it. OTOH fuse-overlayfs can be mounted inside userns with the vanilla kernel (>= 4.18). Signed-off-by: Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp>
