许多模拟器解决这个难题所采取的一个方案是：建立一个针对文件系统调用的额外的解释层。

A solution to this dilemma, adopted in more than one emulator, is to set up an extra layer of interpretation for file system calls.

如果您的程序在模拟环境中运行，那么要访问的文件系统可能与您开发程序时使用的文件系统有本质上的不同。

If your program is running in emulation, the file system you access may be substantially different from the file system you had when you were developing the program.

由于MTD_BLOCK设备提供象块设备那样的模拟，通常更可取的是在这个模拟基础上创建象FTL和JFFS2那样的文件系统。

Since MTD_BLOCK devices provide block-device-like emulation, it is often preferable to create filesystems like FTL and JFFS2 on top of this emulation.
