I have just done a clean install of current (amd64) and upgraded to gcc 4.2 and installed xorg with /usr/local, /usr/src, /usr/obj on zfs. No problems, except that one particular file would make my system swap 1.1 GB a couple of times before the file eventually compiled :-) When I tried to generate a xorg.conf file my machine stopped and I had to push the reset-button. I thought it was a mix of zfs and X so I moved /usr/local from zfs to ufs and disabled zfs and rebooted but it still stopped. After I copied an old xorg.conf X would start fine. So it was probably due to a bad probe. I'm compiling kdebase atm. and still no need to adjust settings. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner. Shakespeare.
