Test 214 and 236 use the same file names for test files in the TEST filesystem and don't check/create clean initial test state. Hence if you run 214 then 236, 236 will fail with: +link: cannot create link `/mnt/test/ouch2' to `/mnt/test/ouch': File exists +ctime: 1277076527 -> 1277076527 +Fatal error: ctime not updated after link Ensure that both tests clean up after themselves properly and also ensure a clean state before they start.
