Or so I've heard. :) I believe we are pretty much just on par and no more than 1 order of magnitude on time completion of make world. > > Having those variables defined in a centralized manner allows us here for > example to convert the result of what would be > installworld/installkernel/distribution action into a self-extracting > archive (optionally signed) with automatically generated script, which does > the action in question.

All of the existing values should of been overridable from the make command line invocation, and it does not mater if they are in 1 file or 50 files. > I have very few reasons to believe that our needs to be unique in this, I > am pretty sure others will find some interesting use for this as well (e.g. > signing binaries being installed, etc).
