From 050af9c4e86eeecd484ed44b7765e750523276eb Mon Sep 17 00:00:00 2001 From: Siddhesh Poyarekar Date: Wed, 29 Aug 2012 10:03:39 +0530 Subject: Don't make ttyname* fail if proc filesystem is not available The ttyname and ttyname_r functions on Linux now fall back to searching for the tty file descriptor in /dev/pts or /dev if /proc is not available. This allows creation of chroots without the procfs mounted on /proc.
