[SOLVED] How does "dist-upgrade" find the intial grub menu.lst options?

[littlebat]

I am using Xubuntu8.04, below is the part content of menu.lst which generated when installed system initially:

root (hd1,0)
kernel /vmlinuz-2.6.24-19-generic root=/dev/md0

Later, I moved my system to another place and edited the menu.lst manually like below:

root (hd0,0)
kernel /vmlinuz-2.6.24-19-generic root=/dev/sda3

When I executed "sudo apt-get dist-upgrade" to upgrade the system, kernel 2.6.24-22-generic was installed newly, when upgrade tool updated "menu.lst", there are some options, the first is "install the package maintainer's version", the second is "keep the local version currently installed", I selected the first option, upgrade tool generated menu.lst come with the options when I installed system initially, like below:

root (hd1,0)
kernel /vmlinuz-2.6.24-19-generic root=/dev/md0

How does dist-upgrade find the menu.lst options of the system installed initally? Where is the system to keep the information of the menu.lst when system was installed initially?

I guess a bug I reported maybe related with this. This bug is ("Segmentation fault" after "apt-get dist-upgrade" for Hardy) https://bugs.launchpad.net/ubuntu/+bug/297546 . But, I can't reproduce this bug and can't find the crux of the problem. Maybe, bug "https://bugs.launchpad.net/ubuntu/+bug/297546" isn't a bug, it was produced by my mistake.

Thanks.

Hi, if anyone have run into the same situation?
I have tried my best to look for the answer, but I failed.

If I didn't express my meaning clearly? Please tell me. My english is a bit poor.

If I understand your problem correctly, you may need to change the line beginning with kopt in your menu.lst:

Thanks. I think you have answered my question. It is the time I learn GRUB deeply now.
