Or so I've heard. :) 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. As such, we can now build in a completely sandboxed environment with 0 privileges (potentially even on something completely alien like GNU/Linux) and then deploy it to as many systems as we need or use to create VM images / Jails. https://github.com/sobomax/sysmaker/blob/master/makeargs/distribution.sub https://github.com/sobomax/sysmaker/blob/master/makeargs/installkernel.sub https://github.com/sobomax/sysmaker/blob/master/makeargs/installworld.sub 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). -Max
