在问题中在哪里可以找到 UNIX 的官方文件层次结构标准？有人写道：
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...
也有人说
That is the standard. The fact that it looks quite old
is a measure of it's success as a standard...
今天的状况如何？哪些 Linux 发行版采用FHS标准认真的和不认真的？
