Used simplifier rules: afs_format#(N, DOSYNC, SIZE, MD; DIRS; FILES, ASYNCED, ERR) {if SIZE = LEB_SIZE then { {DIRS := ∅, FILES := ∅; DIRS := DIRS ++ ROOT_INO; DIRS[ROOT_INO] := mkdir(0, MD, 0, 0, ∅); ASYNCED := true; ERR := ESUCCESS} or {DIRS := ?, FILES := ?, ASYNCED := ?; fail#(; ; ERR)}} else abort };
