`--runtime=io.containerd.kata.v2 -v /foo:/mnt:ro`: `failed to create shim task: ENOENT: No such file or directory: unknown`

[AkihiroSuda]

ctr can create a bind mount for kata:

# ctr run --rm --runtime=io.containerd.kata.v2 --mount type=bind,src=/foo,dst=/mnt,options=rbind:ro docker.io/library/alpine:latest foo cat /mnt/hello
hello

But nerdctl cannot:

# nerdctl run -it --rm --runtime=io.containerd.kata.v2 -v /foo:/mnt:ro alpine cat /mnt/hello
