You could also consider using Kris's trick of running older userlands in chroots on -current (or 6.x in your case) kernels like he does on the ports cluster. I think his BSDCan paper has the details on the bits you need to replace to deal with kernel incompatabilities. The nice that is that you don't have any emulation in the way. I think Peter Wemm said they were also doing i386 chroots on amd64 kernels at Yahoo! so that may deal with that issue. At least until 7.0 comes you should be able to do -current buildworld and buildkernel on 6.x machines so that won't be a problem (if it is, scream since breaking that is bad :). -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
