Eric efadc0e299 Allow multi-user installations (#1804) ... When re-using previously downloaded tarballs, spack copies from `var/spack/stage/PACKAGE-VERSION-HASH/downloaded_file` to `var/spack/cache/PACKAGE/downloaded_file`. This fails if the source is owned by a different user (`shutil.copy` tries to retain all meta data including file ownership). Change to a non-meta-data copy function (`shutil.copyfile`).		2016-09-20 02:18:26 -07:00
