--000000000000b1111d0603443a25 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hello. For example some time ago I started an email exchange with a FreeBSD developer because I'd found two bugs. You can see our full log here : https://pastebin.ubuntu.com/p/HvVC9pkgVB/ I've removed the name of the developer. Anyway he said that he was investigating,but at some point he stopped to reply. So I don't know if the bugs are already there or not. Or if he has submitted them. I'm not experienced,but I suspect that those kinds of bugs aren't caused by the kind of userland,but at a level of abstraction layer. So,if you change userland,you will not fix them.
