Cannot profile R processes created from Podman containers

[atheriel]

Attempting to profile a process created by podman in rootless mode, e.g.

$ podman run -dt docker.io/r-base

Yields a permissions issue on the process's root directory from procfs:

$ xrprof -p <container pid>
error: Cannot open /proc/145388/root/usr/lib/R/lib/libR.so: Permission denied
fatal: Failed to initialize R stack cursor.
