Hi, Indeed, wifibsd is a subtractive process of what we might call "sysgen" scripts, for post buildworld, as I explained to Sean in IRC. I really like nanobsd because it doesn't waste my time (just like picobsd) building all the things that I would just filter out with custom lists of files. Warner said something about a post buildworld system of exclusion for the installworld target, and I'd really like to see us go this way too. Both methods in terms of speed to deploy, and flexibility to hack (NO_FOO=YES vs installworld exclusion lists) would be ideal. Mainly nanobsd is nice because I get tired of crunching, and crunchgen. Since it is default to have dynamic bins FreeBSD is already as near picobsd it can be without crunching. To me this alone makes 5.x more ideal for embedded projects are things like devfs, default small dynamic world. I've thought about making a wifibsd version of nanobsd just to see if I can. From what I read this shouldn't be too difficult to customize (my list of files to include). I created wifibsd sysgen scripts in a fit of rage toward using picobsd and crunching, but nanobsd does what I really always ever wanted. If anybody is wanting, I'd be willing to help 5.x'ize the picobsd scripts? I see no reason to have backward compatibility with 4.x, and I have basicaly everything ready to go directly form my wifibsd scripts. To those who have contributed to picobsd, please don't take offense, but picobsd scripts are ugly. and I can help make them not ugly. Nanobsd is a welcome additon to the embeded community. thanks! -Jon (aka masta) Bruce R.
