Re: Building a Linuxulator userland from source

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 :

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.
