-Subject: [PATCH] deploy: Correctly use libmount unref() calls rather than
- free()
-
-We saw a random ostree SEGV start popping up in our CI environment:
-https://github.com/projectatomic/rpm-ostree/pull/641#issuecomment-281870424
-
-Looking at this code more and comparing it to what util-linux does, I noticed we
-had a write-after-free, since `mnt_unref_table()` will invoke
-`mnt_unref_cache()` on its cache, and that function does:
-
-```
-	if (cache) {
-		cache->rfcount--;
-```
-
-unconditionally.
-
-Fix this by using `unref()`.
