update-grub将vga=791 resume=/dev/sda9清除了

marvel

原来我配置好了menu.lst
其中有

122 title       Debian GNU/Linux, kernel 2.6.24-686
123 root        (hd0,7)
124 kernel      /vmlinuz-2.6.24-686 root=/dev/sda10 ro vga=791 resume=/dev/sda9
125 initrd      /initrd.img-2.6.24-686
126
127 title       Debian GNU/Linux, kernel 2.6.24-686 (single-user mode)
128 root        (hd0,7)
129 kernel      /vmlinuz-2.6.24-686 root=/dev/sda10 ro single
130 initrd      /initrd.img-2.6.24-686
131

但是当运行了update-grub之后，vga=791 resume=/dev/sda9就不见了。

即使我设置了defoptions=vga=791 resume=/dev/sda9也不行，只要一运行update-grub就清除了

有没有办法保留这个字段呢？

Debian 的更新脚本很愚蠢，更新内核前最好将原来的 menu.lst 备份，更新後再手功加回来

另一个不正常的蠢 bug 就是如果 /boot 是独立分区，那麽更新内核後其路径必然是错的！

不要过份依赖发行版的更新脚本，靠自己吧。。。

问题是每次安装内核或升级内核之后都需要更新grub的，sigh

非也，不是要更新 grub，是要更新 menu.lst

tomgrean

下面的就是我的menu.lst文件，可没小看文件里的注释，在“## ## Start Default Options ##”后面直到“## ## End Default Options ##”处的“##”才表示注释，面单个的“#”对grub是注释，对update-grub是配置文件！

2. # menu.lst - See: grub(8), info grub, update-grub(8)
