Glossary

AFS

A networked filesystem that is widely deployed at MIT and CMU. scripts.mit.edu serves files from AFS.

pristine

The branch containing clean, unmodified copies of application code straight from upstream, though possibly with blank .preserve-dir files added to empty directories to preserve their existence in Git.

versions store

The directory residing in /mit/scripts/sec-tools/store/versions. It is generated by parallel-find.pl (found at /mit/scripts/sbin/parallel-find.pl) and conventionally contains one file per locker, each containing install lines for every autoinstall in that locker. This directory is used for determining what “all autoinstalls” means and can be overridden using --versions-path. A file can also be a versions store.
