How long until those L-people move the BSD people aside? ZFS was on Linux years ago, but only as a third-party solution, it won't gain much traction there since kernel devs refuse to keep it in the upstream kernel due to licensing issues and distribitions refuse it install it by default, and people are either still waiting for the vapourware Btrfs or losing heir data to it instead :-D. On FreeBSD, ZFS is integrated into our tree (as is other outstanding CDDL licensed software from Sun, like DTrace which puts Linux's systemtap to shame), and we already boot from it :-). Oh and doesn't FreeBSD also participate in OpenZFS? Systemd is not so much "on Linux" nor a big success there, when Slackware doesn't use it, Debian was forked to run without it, Gentoo doesn't use it by default, and it is broadly hated to the degree that it is driving Linux users to FreeBSD :-). > Well, asking for Haswell support is a bit weird - Skylake ante portam. > Broadwell is already there.

Broadwell at best half-works on Linux and has major issues: crashes, broken suspend/resume, poor support for multiple monitors, and broken console view (http://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/intel-linux/809842-intel-has-a-ton-of-developers-working-on-their-linux-graphics-stack?p=809940#post809940). NVidia on the other hand supports FreeBSD and works well. Linux copies many WiFi drivers from OpenBSD. Have you tried the WiFi card's Windows driver with NDISulator? What we could also do in future is use a similar idea to use Linux WiFi drivers on FreeBSD. > Interesting to hear that DragonFlyBSD seems to have solved several iGPU issues > and FreeBSD not.
