Which program? I hope not that crappy splashy? It wrecks your menu.lst very easily. After two years of using a debian its in my top 5 worst package I have seen.

This kernel-img.conf only works for new kernel-image installation, I was maybe not clear.

Yes you are right. I was talking about splashy. Your guess is right. Just out of curiosity, can you tell me why splashy is bad?

When I tried it, it had overriden my kopt values in menu.lst as if it did not use update-grub but its own mechanism. I then copied back a backup of this file. But what really annoyed me is that it left the /etc/init.d/splashyxx after uninstalling it. So I deleted them. I'm a bit fussy but it never happens in general with debian.
But that's my own opinion and maybe now it is corrected.
The positive thing is that it is in user space while bootsplash is in kernel space and I'm not sure its a good thing to have a bootsplash in kernel space (the only advantage of this is that it can run earlier)

Interesting views. It is always good to share views and ideas. Well I am not sure which version of splashy you used, but I am running this version splashy_0.1.5.svn28_i386.deb and it runs pretty good except updating the menu.lst file(which is now corrected by using the kopt technique, thanks to bobbens).

As I said my biggest problem while when uninstalling it so you'll see :)
