From 090e71e7fd122a176f65a08189ac2324f073d826 Mon Sep 17 00:00:00 2001 From: Icarus Sparry Date: Tue, 26 Jan 2010 13:16:03 -0800 Subject: [PATCH] os: in test, allow Hostname to return FQDN even if /bin/hostname does not Hostname reads the file /proc/sys/kernel/hostname to determine the value it returns. Some people set this to a Fully Qualified Doamin Name. At least one implementation of /bin/hostname truncates the name it gets (often from the "uname" system call) at the first dot unless it is given a "-f" flag. This change makes the unit test also truncate at the first dot and checks if the strings then match. This seems more portable than adding an extra flag to the called /bin/hostname program.
