This is consistent with several comments by Linux Tovalds, couple years ago."In addition to re-focusing on solely on ZFS as our default file system, we have had to take a look at the feasibility of continuing with the i386 builds. As many of you know, ZFS is a 21st century operating system that doesn't play nicely with the legacy i386 kernel / versions of FreeBSD. In addition, over the past couple years, more and more of time-consuming issues we've encountered have been only on i386, partly due to the fact that most FreeBSD developers have already moved on to 64-bit systems and also due to the quickly shrinking number of users / systems that still run i386. In order to make PC-BSD and TrueOS secure, stable and timely, we've decided to drop the i386 builds going forward, and instead focus on a single 64-bit architecture. This means that the next editions of rolling-release and 9.2 onward will be 64-bit only."
Many will object, but, he appears to be firm about his resource commitments and the direction.
