From ffe00a05229ef58272669dea141e9fa33e07a5ee Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Tue, 2 Sep 2025 23:17:35 -0600 Subject: [PATCH] rc.d/serial: Kill dtrwait The dtrwait wait functionality was dropped in the TTY MPSAFE rewrite for FreeBSD 8. Remove referneces to it here. Also, the sysctl was renamed for drainwait, so use the new name. Given the 16 years between this event and somebody noticing, I strongly suspect this file can just be removed.
