+// into `inaccessible/tmp`. Ideally, the riscv64-gnu docker container
+// would use a non-root user, but this leads to issues with
+// `mkfs.ext4 -d`, as well as mounting a loop device for the rootfs.
 //@ ignore-arm
 // Reason: linker error on `armhf-gnu`
 //@ ignore-windows
 // Reason: `set_readonly` has no effect on directories
 // and does not prevent modification.
