no 'last good boot' entry in GRUB menu

I also have the same problem.
I first installed kubuntu 8.19 beta on a partition. After that I deleted my other partitions and merged them with my kubuntu partition. That screwed my grub and I had to grub-install from my live cd. After that there is no last good boot and As mentioned in the bug report i dont either have /boot/last-good-boot nor /lib/modules/last-good-boot

sorry kubuntu 8.10 beta

This spec was rolled back for intrepid due to problems with the implementation.

So this is not a bug. The feature itself has been removed?
Any plans for re introducing it?

If I want to create something like that by hand, which files & directories I should copy to make sure it's operational?

The reason why I want to do it is that recent kernel updates are just incremental updates to the same kernel. I personall experienced a problem when latest update broke the WiFi support (it was fortunately resolved in couple hours, but it was really troublesome)

I know it's devel relase so things like that are normal, that's why I want to protect myself from that in the future,
My laptop doesn't have cd-rom and floppy drives, so if kernel would make system unbootable, I'll have to play with PXE again :(

After looking at grub logfile I found that the setting to enable/disable this feature is located in /etc/defaults/kernel-helper-rc (I'm writing it from memory).

After commenting a line there, it comes back and appears to work as before.

Now the question is, what was the reason to disable it?
What I should look for? And how dangerous it is?
The changelog didn't mention much besides just disabling it.

i had the same problem with "Last successful boot", when are you going to implement it again?

the feature is disabled by a line in the file /etc/default/kernel-helper-rc
it was not considered stable by the ubuntu developers and was therefore disabled (but not removed)
anyone wishing to enable it again can simply edit this file

i have also updated the wiki page accordingly

Dimitrios, what kind of potential problems does it cause?
How safe is it?

I don't think it's a safety problem, I think it was not considered
good enough to be used as a stable fall-back solution.

What I mean is that it probably wasn't working as expected.
