From 0c78757010a17173bdc79b818133697e7dcbf6a4 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Mon, 17 Nov 2014 15:06:35 +0100 Subject: close leaking slave fd after setting up pty magic The fd moves out of scope here anyway, so we should close it properly instead of leaking it which will tickle down to dpkg maintainer scripts.
