hal-set-property修改lshal信息

对于使用gnome-mount或者hal的朋友来说，当分区被挂载后，会在桌面上显示”多少G的设备“这样的东西，是不是看着眼烦，现在介绍一种比较简单的方法来修改hal的参数
首先，使用hal-device,来查看自动挂载信息，例如hal-device |less 然后查找sda5
代码:

这里的全部都是关于hal自动挂载sda5的信息，上面的信息都是可以改动的。
现在我们要做的就是改动上面的信息，我们使用hal-set-property，来改变他们的值(这个命令需要root用户权限)。
通 常情况下使用这样的命令结构，hal-set-property --udi 设备的udi值（udi，相当于hal挂载设备的id是唯一的） --key 要改的键(如要改标卷volume.label) 然后接要改的值的类型 (--string 表示值为字符串, --int 值为整型，--bool 值为布尔) 后面为具体的值。
例如，我们要修改sda5的自动挂载的挂载点，让他固定而非disk-x，
hal-set-property --udi /org/freedesktop/Hal/devices/volume_uuid_EE0454B90454868D --key volume.mount_point --string /media/winE
hal-set-property --udi /org/freedesktop/Hal/devices/computer --key system.hardware.product --string "PowerEdge R610"
hal-set-property --udi /org/freedesktop/Hal/devices/computer --key system.hardware.serial --string "H5C3X3X"
