I forgot to mention in the first email: I'm running Ubuntu 20.04 in a RISC-V QEMU image, so it's not exactly your standard setup. I've also made an interesting observation. If I descend to the very bottom of the directory tree, I can trigger the following behaviour: ``` $ mkdir b $ ls a b $ rmdir b rmdir: failed to remove 'b': File name too long ``` (the file 'a' was created from an earlier experiment.)
