在問題中在哪裡可以找到 UNIX 的官方檔案層次結構標準？有人寫道：
As with all things unix, it's less of a law and more of a guideline;
how much of it is adhered to varies by distro and flavor...
也有人說
That is the standard. The fact that it looks quite old
is a measure of it's success as a standard...
今天的狀況如何？哪些 Linux 發行版採用FHS標準認真的和不認真的？
