## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
##      kopt_2_6_8=root=/dev/hdc1 ro
##      kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=d72fd170-80fb-43da-b079-e51cd1a06a7c ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,2)

## should update-grub create alternative automagic boot options
## e.g. alternative=true
##      alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
##      lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

## should update-grub lock old automagic boot options
## e.g. lockold=false
##      lockold=true
# lockold=false

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
##      altoptions=(single-user) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
##      howmany=7
# howmany=all

## should update-grub create memtest86 boot option
## e.g. memtest86=true
##      memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## ## End Default Options ##

为什么要这样,有什么优点...这样要配置起来可就费劲了

I agree!
Why use the UUID?

每个硬盘驱动器都有一个独特的标志,叫做 UUID。要解决设备名称的变动问题,devlabel 允许你使用用户定义的设备名称来关联这些 UUID。一个符号链接会被创建来连接用户定义的设备名称和实际的设备名称。如果实际的设备名称改变了,这个符号链接会被更新,并根据驱动器的 UUID 来指向同一驱动器。因此,IDE 和 SCSI 贮存设备都可以使用它们的用户定义的名称被引用。

Devlabel 还允许你自动挂载热插入的设备,如可移硬盘和数码照相机的内存卡之类的 USB 设备。如果被配置成自动挂载,设备被插入后,它就会使用用户定义的设备名称被挂载。

uuid那么长看着就烦
linux什么最重要?硬件要旧,软件要新!
Ubuntu什么最重要?源要全!网要快!
不是你不明白,是linux变化快
人品也很重要
