Yes, but also no: there certainly can be differences in behavior that are allowed by the interface (where it explicitly doesn't guarantee something), but (due to bugs) can influence the outcome. For instance, does every write to /dev/null always write the whole buffer, or can there be short writes?
@civodul
Or: can a signal interrupt a write to /dev/null? (On SerenityOS the answer used to be no, on the Hurd it's a resounding yes, dunno about Linux.)
