In fact this message doesn't even come from su, but from the users shell. Once the shell execs we're past su already. > > # su -c : nobody|wc > 1 6 41 > # su -c : nobody > This account is currently not available. The message in question comes from "nologin" program (which in debian is built from src:shadow, not src:util-linux even though both implementations are outputting to stdout rather than stderr). The entire purpose of the nologin program is to display a human friendly greeting message, which thus makes sense to write to stdout rather than stderr. How ever weird it may seem, the message indicates everything worked as expected an no error occured! :P My conclusion is thus that this peculiarity is "by design" rather than a mistake. (And personally I don't see much value in the "nologin" tool at all, would be better to just have such login attempts fail with a proper error message.) I'm thus tagging this as wontfix. If you disagree with that, then please go discuss this with the people who have actual influence over the design upstream (but I guess they might feel they're not responsible for ancient unix design and might feel uneasy about changing the heritage). > > instead of STDERR! > FWIW, the util-linux source has this message at: https://sources.debian.org/src/util-linux/2.33.1-0.1/login-utils/nologin.c/#L87 (And finding it in src:shadow is left as an excersise to the reader.)
