I've investigated LTIB and Yocto but both do not fulfill my needs. There are two many issues with both of them in installing software where there shouldn't be any issues (such as ruby, httpd, passenger...).
I don't want to start a debate, I like yocto philosophy, I just don't have the time to fill the gap between it and a mainstream distro
With my variscite board (iMX6) came a ubuntu distro. Where does it come from ? I plan to start a minimal debian so I assume I just need to cross compile the kernel with the same patches I use in ltib & yocto, but if there's a guideline about how this ubuntu distro has been generated, that would be really helpful !
