And nobody contacted me so far to ask about this entry on the ideas list. As I get several requests for other entries from time to time (without that someone produces something) I conclude (based upon my experience with the ideas list): - most people think this entry is too advanced for them - nobody is looking into it >> 5/ discuss your changes and keep us up to date in arch@freebsd.org >> for initial discussions on ideas and current@freebsd.org when you >> are implementing and need >> to discuss things with people. I would add: if there are parts which are too advanced for you, just ask on the lists. There are people out there which may be able to help. Don't be afraid if something looks too big. If you go closer there are always things you can do yourself, and if not... just ask on the lists (arch@/current@). >> 6/ announce calls for testers and code drops when you are near completion. >> >> 7/ take a vacation. >> >> Except for politeness (not stepping on other people's work) you don't need >> to ask permission to do any work on this or any FreeBSD component. >> >> If the work is good and well documented, and passes a good review, it will >> be accepted back. And to make it good and accepted, a good thing to do is to keep the people up to date. Provide access to your work (e.g. posting links to patches) and discuss various things on the lists. There are also people which are willing to test changes (warn them if the changes are in areas where a bug may result in data-loss), and there are always edge-cases which you don't find yourself but broad testing will reveal. Use the possibilities the lists provide (testers, reviews, opinions) and you are on a good way to get an useful end-result. Bye, Alexander. -- I can't decide which WRONG TURN to make first!!
