https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202127 Jilles Tjoelker <jilles@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jilles@FreeBSD.org --- Comment #2 from Jilles Tjoelker <jilles@FreeBSD.org> --- In the general case this cannot be solved because the password prompt needs different code and data and may therefore require things to be paged in (slowly). When utilities like su and sudo are also considered, the user will have to wait for Password: before typing their password. In particular, whether the password prompt is displayed at all and how it looks like depends on the passwd file (empty password = no prompt, logs in immediately) and the PAM configuration (e.g. showing OTP sequence number). What's more, the initial login: prompt on ttyv* uses getty(8) and the password prompt (if any) comes from login(1), so even more code needs to be loaded for the password prompt to show. It may be possible to modify the protocol between getty(8) and login(1) to start without echo tty mode, so that too early password characters are at least very unlikely to show up. login(1) will have to skip some tty flushes and enable echo mode later on. -- You are receiving this mail because: You are the assignee for the bug.
