If I'm not remembering that right ignore this... If I am remembering that right don't the statfs issues break that, or at least make it something not to be attempted by mere mortals and perhaps worth a mention in UPDATING? Based again on possibly flawed recollections I thought general concensus was when upgrading from pre-statfs change systems to post-statfs changes you should not only make sure you do the 'buildkernel' before 'installworld', but you should also make sure to reboot with that kernel before doing the 'installworld'. But it's installworld that puts most of the new goop in /boot that goes looking for the kernel in the right place, and the thought of a 5.X kernel using 4-STABLE variants of the things it takes to get to single-user mode sounds scary. -- Ken Smith - From there to here, from here to | kensmith@cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel |
