Am I wrong to do so? For the initial install it's definitely a good idea to have a UP kernel. One of the recent machines I installed Fedora on did not work with a SMP kernel (for reasons I never figured out), but it worked well on UP and I had no immediate need for a second CPU. Once you have a machine running well on SMP there is no real need for a UP kernel (IMHO). If you upgrade to a new SMP kernel which breaks then you can go back to the old SMP kernel which will often be a better choice than a new UP kernel. Would it be possible to have a UP kernel not get upgraded on a SMP system? -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
