Re: What about adding AT_NO_AUTOMOUNT analogue to openat2?

* Aleksa Sarai:

It would just give you -EXDEV (or perhaps -EREMOTE) if you walk into an
automount (the same logic as with the other RESOLVE_NO_* flags). We
could make it -ENOENT if you prefer, but that means userspace can't tell
the difference between it hitting an automount and the target actually
not existing.

Maybe there's a better way to show the difference to userspace
involving something related to O_PATH?
