更改ubuntu的挂载点.doc

我的是给ubuntu的空间太少了`但是主要工程都是在home下，所以格式化了一个空间来作为home，然后挂载到/下

以root权限，在终端的窗口里输入命令，找到你要挂载的分区，这里以sda5为例
$fdisk-l
Disk/dev/sda:320.1GB,320072933376bytes255heads,63sectors/track,38913cylindersUnits=cylindersof16065*512=8225280bytesSectorsize(logical/physical):512bytes/512bytesI/Osize(minimum/optimal):512bytes/512bytesDiskidentifier:0xf517e314DeviceBootStartEndBlocksIdSystem/dev/sda1*1522241945683+7HPFS/NTFS/dev/sda2522377121999974483Linux/dev/sda377127961199987282Linuxswap/Solaris/dev/sda47962389132486219405Extended/dev/sda579621768778124063+83Linux/dev/sda61768825520629185417HPFS/NTFS/dev/sda725521389131075792417HPFS/NTFS
这里可以看到/dev/sda5，这应该是我想挂载在home下的分区。察看sda5的UUID
$ls-l/dev/disk/by-uuid
看一下sda5的UUID
