/**
 * Tests for sharing files and directories
 *
 * We systematically test the various Vfs backends with files, subdirectories
 * and symlinks.  A backend is mounted (if needed) and test files are created.
 * Then we create the share (readable, writable) log out and check what the share
 * gives.  This is compared against what should be available, and we check the
 * access on each.
