ArchLinux下通过Grub2引导进入GPartedLive动态调整分区大小

版本：

┌─[root@tp]─[/etc/grub.d]─[9+0]─[99%=]

└─# cat /proc/version

Linux version 3.7.9-2-ARCH (tobias@T-POWA-LX) (gcc version 4.7.2 (GCC) ) #1 SMP PREEMPT Mon Feb 25 12:04:25 CET 2013

┌─[root@tp]─[/etc/grub.d]─[9+0]─[99%=]

└─#

下载gparted live文件并解压，注意这里的boot是单独分区

(http://voxel.dl.sourceforge.net/project/gparted/gparted-live-stable/0.14.1-6/gparted-live-0.14.1-6-amd64.zip)

unzip gparted-live-0.14.1-6-amd64.zip -d /boot/gpartedlive

调整分区列表，计划将根分区减小10GiB，/var分区增加10GiB

┌─[root@tp]─[/etc/grub.d]─[9+0]─[99%=]

└─# df -h | grep sd

/dev/sda2 40G 5.3G 33G 14% /

/dev/sda3 9.9G 2.6G 6.8G 28% /var

/dev/sda1 1008M 199M 758M 21% /boot

/dev/sda6 405G 338G 47G 88% /home

┌─[root@tp]─[/etc/grub.d]─[9+0]─[99%=]

└─#

复制一份自定义grub菜单文件用做gparted live启动菜单

cd /etc/grub.d/

cp -av 41_custom 50_gpartedlive

重启并选择新增的菜单"GParted Live 0.14.1-6 (03-Mar-2013)"进入gparted live系统，进行具体的分区大小调整，全是类似PQ Magic的图形化操作，这里不再详述。

调整完后，重启，检查结果
