Setting up various filesystems like proc, ext2, jffs2.
建立各种文件系统，如proc、ext2和jffs2。
JFFS2 maintains block lists to sufficiently wear-level the device.
JFFS2通过维护块列表来充分地对设备执行平均读写。
The current version of JFS on flash is JFFS2 (described later in this article).
用于闪存的JFS的当前版本是JFFS2(稍后将在本文中描述)。
The kernel configuration and compiling of JFFS2 are introduced in this paper as well.
并介绍了JFFS2文件系统的内核配置及编译方法。
The JFFS2 filesystem is log-structured, meaning that it is basically a long list of nodes.
JFFS2文件系统是日志结构化的，这意味着它基本上是一长列节点。
Hardware drivers need not know about the methods employed by user modules like JFFS2 and FTL.
硬件驱动程序不需要知道象JFFS2和FTL那样的用户模块使用的方法。
A jffs2 filesystem (basically a Ramdisk using jffs2) is created under Linux with the mkfs.jffs2 command.
在Linux下，用mkfs .jffs2命令创建jffs2文件系统(基本上是使用jffs2的Ramdisk)。
The second version, JFFS2, is emerging as the de facto filesystem for raw flash chips for tiny embedded devices.
第二个版本，JFFS2，作为用于微型嵌入式设备的原始闪存芯片的实际文件系统而出现。
The JFFS2 algorithm was designed for NAND flash devices and also includes improved performance with compression.
JFFS2算法专门为NANDflash设备设计，并且改善压缩性能。
Having been written primarily for use with flash devices, the disadvantages of using JFFS2 in an embedded environment are few.
因为本文主要是写关于闪存设备的使用，所以在嵌入式环境中使用JFFS2的缺点很少。
Saving data in JFFS2 file system runs simply, which is more suitable to embedded environment compared with traditional data-base.
JFFS2文件系统保存数据简单快捷，占用空间少，跟传统的数据库相比更适应于嵌入式环境。
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.
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。
Perhaps most importantly, JFFS2 was specifically created for embedded devices like flash chips, so its overall design provides better flash management.
这可能是最重要的一点：JFFS2是专门为象闪存芯片那样的嵌入式设备创建的，所以它的整个设计提供了更好的闪存管理。
This example shows ext3, but the Journaling flash File system version 2 (JFFS2) and SquashFS are also good choices, particularly for flash-based storage systems.
这个示例使用ext3，但是JournalingFlashFileSystemversion2 (JFFS2)和SquashFS也是合适的选择，尤其是对于基于闪存的存储系统。
This is done by using JFFS2 (Journaling Flash File System version 2), which compresses stored data; the 21,544 blocks of storage available hold roughly 60,000 blocks of files.
这是通过使用JFFS2（JournalingFlashFileSystemversion2）实现的，它会对所存储的数据进行压缩；这 21,544 个存储块可以容纳大约 60,000 个文件块。
Unlike most other filesystems like Ext2fs and JFFS2, which reside on top of the underlying block device, TMPFS sits directly on top of the VM. Thus mounting the TMPFS filesystem is a simple affair.
诸如Ext2fs和JFFS2等大多数其它文件系统都驻留在底层块设备之上，而tmpfs与它们不同，它直接位于VM上。
