grub不使用/etc/default/grub中的设置

Question

我设置了一个新的ubuntu系统，并按如下方式编辑了/etc/default/grub：

# If you change this file, run update-grub afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo
#GRUB_GFXMODE=640x480

# Uncomment if you dont want GRUB to pass "root=UUID=xxx" parameter to Linux
GRUB_DISABLE_LINUX_UUID=false

# Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_LINUX_RECOVERY=false

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

之后，我运行了update-grub，它没有报告错误。但是，/boot/grub/menu.lst在内核命令行中仍然有“安静的启动”：

title   Ubuntu, kernel 3.5.0-17-generic
uuid    3f26e165-5167-43e5-8fa2-aa55f7919d2a
kernel    /boot/vmlinuz-3.5.0-17-generic root=UUID=3f26e165-5167-43e5-8fa2-aa55f7919d2a ro quiet splash 
initrd    /boot/initrd.img-3.5.0-17-generic
quiet

title   Ubuntu, kernel 3.5.0-17-generic (recovery mode)
uuid    3f26e165-5167-43e5-8fa2-aa55f7919d2a
kernel    /boot/vmlinuz-3.5.0-17-generic root=UUID=3f26e165-5167-43e5-8fa2-aa55f7919d2a ro  single
initrd    /boot/initrd.img-3.5.0-17-generic

如何才能解决它，所以摆脱“安静”和“飞溅”的选项？

Answer 1

正如您所知，12.10 (以及几乎大多数其他Ubuntu版本)使用的是Grub2，而不是Grub。其中一个Grub和Grub 2包的主要区别是没有/boot/grub/menu.lst文件，它已经被/boot/grub/grub.cfg替换了。

对/etc/default/grub的更改不会更新/boot/grub/menu.lst文件，而命令update-grub实际上只更新/boot/grub/grub.cfg文件。

因此，如果要检查/boot/grub/grub.cfg文件，您可以注意到内核命令行将不再有“安静的启动”。
