Sometimes you have no access to the file system (nothing mounted, you're chrooted, ro mounts, ...). It would be nice if rumur-run still worked in such cases. This looks achievable on Linux using memfd_create and fexecve. I don't know how we can achieve this on other platforms, but Linux may be the only one where this situation regularly arises.
