Ubuntu 8.10 "Intrepid" Alpha 5 Released
On top of that, Ubuntu now is retaining a copy of the last successfully booted kernel in the event a new kernel fails. This is good as it allows the older kernels to be automatically removed, but still provides one level of fall-back in case the latest kernel goes awry. Last but certainly not least, Ubuntu 8.10 will ship with DKMS by default. DKMS, or Dynamic Kernel Module Support, is a project of Dell's that allows out-of-tree kernel modules to be rebuilt automatically when switching to a new kernel. A notable user of this technology is ATI with their Catalyst Linux driver.
