From f7afb6b6b850c25e09140e0cd75c6c517f5685c4 Mon Sep 17 00:00:00 2001 From: Sami Kerola Date: Sun, 18 Aug 2013 09:51:46 +0100 Subject: docs: add note to wall(1) about sessions which will not get message Sessions that has in utmp data ut_line begining with ':' are skipped. This is done to avoid write errors to devices such as '/dev/:0'. For example wdm is reported to to generate such utmp line. Perhaps in future this code should be revalidated. If an utmp data contains broken device lines it might be best inform user with a error message, rather than skipping silently suspicious device entries.
