From 8236d57439640a185c0226312cd4903a3ce2f53b Mon Sep 17 00:00:00 2001 From: Alex Franco Date: Fri, 28 Aug 2015 17:34:04 -0500 Subject: Fix mode +st on TMPDIR when creating it A sanity check fails when TMPDIR has setuid, setgid set. It was proposed to fix this on TMPDIR creation instead of failing with a sanity test only. This patch handles removal of those special bits (and additonally, the sticky bit) from BUILDDIR and TMPDIR when these directories are created.
