Problems running shim exampe skeleton

[dierbei]

I first tried to build the project:

root@ecsHyNL:~/dierbei/rust-extensions# cargo build --example skeleton

Tried to run the program after that, but it failed.

root@ecsHyNL:~/dierbei/rust-extensions# ctr run --rm --runtime ./target/debug/examples/skeleton docker.io/library/hello-world:latest hello
ctr: failed to start shim: start failed: : exec: "/": permission denied: unknown

Containerd version:

root@ecsHyNL:~/dierbei/rust-extensions# containerd -v 
containerd github.com/containerd/containerd v1.7.2 0cae528dd6cb557f7201036e9f43420650207b58

OS:

root@ecsHyNL:~/dierbei/rust-extensions# uname -a 
Linux ecsHyNL 5.15.0-79-generic #86-Ubuntu SMP Mon Jul 10 16:07:21 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

runtime is assigned by pre-defined config from containerd config file, not support by specific binary file
