This doesn't solve the problem of different versions of userland tools required. For example, my machne is RELENG_6, but I'm developing against the -CURRENT branch of code synced up in perforce. Does one necessarily need a -CURRENT userland to develop with the - CURRENT code base? All arguments of being able to test the code that is built are moot since the testing of my code will all occur within a virtualized (Qemu) machine environment. I'm sure the difference in versions between RELENG_6 and CURRENT aren't too great, but what about developing with CURRENT code on RELENG_5? I guess the basic question is, how can I maintain my normal workstation environment while using a toolset appropriate for building CURRENT? (Does it even matter really?) Cheers, - -R.
