Description
Run a rootless container whose rootfs is set to /sdcard/hello/rootfs
$ run --root ./runc run hello
container_linux.go:296: starting container process caused "process_linux.go:398: container init caused \"rootfs_linux.go:58: mounting \\\"devpts\\\" to rootfs \\\"/sdcard/hello/rootfs\\\" at \\\"/sdcard/hello/rootfs/dev/pts\\\" caused \\\"operation not permitted\\\"\""
proc and tmpfs worked well. I don't know why devpts failed.
Is something missing about namespace or cgroup?

Research direction
Read the stack-trace locations container_linux.go, process_linux.go, and rootfs_linux.go, then reproduce the rootless run with /sdcard/hello/rootfs and compare the successful proc/tmpfs mounts with devpts. Confirm the missing permission or setup requirement; done means devpts mounts successfully or the supported limitation and required configuration are recorded.
