I had a situation where I found that /boot had filled up. So I cleared up some space, then reinstalled the most recent kernel images in case the kernels were corrupt. I used:
apt-get install --reinstall linux-2.6.32-33-server
(as one example). Now these reinstalled kernels will bomb out during reboot with a message
Unable to locate init. (or similar).
I could fix this the hard way - by pulling apart the images and finding out why it doesn't work. The root volume is an LVM logical volume formatted with ext4, and the boot GRUB entries match other working entries.
However, I'm sure there's a reason that the package doesn't seem to get it right. I'd like to figure out if I'm doing something wrong with the packages, or if it is something else.
Why won't these reinstalled kernels (installed with APT) boot successfully?
