Linux通过分区来管理文件，在安装系统的时候建议把/home/目录单独mount到一个分区，这样下次重装系统的时候会方便很多。
例如：
mount /etc/sda5 /home
mount /etc/sda6 /work
mount不会在开机自动运行，可以通过配置实现文件系统的自动挂载。
在/etc目录下有个fstab文件，它里面列出了linux开机时自动挂载的文件系统的列表
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda1 during installation UUID=195f527d-dcc0-4773-b461-18f1bdff0a58 / ext4 errors=remount-ro 0 1 # swap was on /dev/sda3 during installation UUID=f36148f5-9239-402e-9696-36affd85fe17 none swap sw 0 0
添加一行：
/dev/sda5 /duitang ext4 defaults 0 0
修改之后立即生效:
mount -a
卸载mount
umount /mnt/usb
