-# On a filesystem that lacks SANITY, a file can be deleted even if
-# the containing directory doesn't have write permissions, or a file
-# can be accessed even if the containing directory doesn't have read
-# or execute permissions, causing our tests that validate that Git
-# works sensibly in such situations.
+# SANITY is about "can you correctly predict what the filesystem would
+# do by only looking at the permission bits of the files and
+# directories?"  A typical example of !SANITY is running the test
+# suite as root, where a test may expect "chmod -r file && cat file"
+# to fail because file is supposed to be unreadable after a successful
+# chmod.  In an environment (i.e. combination of what filesystem is
+# being used and who is running the tests) that lacks SANITY, you may
+# be able to delete or create a file when the containing directory
+# doesn't have write permissions, or access a file even if the
+# containing directory doesn't have read or execute permissions.
