Just to clarify a little, LinuxCNC uses a Linux kernel that is patched with RTAI to provide real time functions. If you look in your /boot directory you should see some files labeled as generic or rtai. By default, your computer should be set up to boot from the rtai patched kernel, but if you do a kernel update the new unpatched kernel will be set as your new default. If you knew how to patch the new kernel and set up grub, you'd be okay, but then your feet would not touch the ground when you walk. If you first install generic Ubuntu 10.04, then use the LinuxCNC script: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_EMC2#On_Ubuntu_10_04_using_precompiled_EMC2_packages you should get a menu during boot-up allowing you to choose which kernel to boot from. You should be able to update the generic kernel and keep the LinuxCNC boot option intact, but I haven't tried this so I'm not sure.
