Proof step 1 from proof lastlink-rename (conclusion)

⊦ # links(entries[str0], dirs) = 1 ∧ ino ∈ dirs ∧ dirs[ino] = mkdir(m, md, n, n0, entries) ∧ str0 ∈ entries ∧ str1 ∈ entries → (entries[str0] = entries[str1] ↔ str0 = str1)

System applied rule normalize

And obtained the following new goals

Proof step 2:
# links(entries[str0], dirs) = 1, dirs[ino] = mkdir(m, md, n, n0, entries), ino ∈ dirs, str0 ∈ entries, str1 ∈ entries ⊦ entries[str0] = entries[str1] ↔ str0 = str1
