I did not try to say FreeBSD should support the old SGI iron. I only wanted to state the fact that luckily there are alternatives which being branches of the BSD family have pretty similar behavior and general feel to them. Nobody needs to change ones brain completely to start using another BSD variant for a while. No worries. --jau > On 23 Apr 2018, at 17.49, Warner Losh <imp@bsdimp.com> wrote: >=20 > There's a lot of work to support these devices, and there's not a lot of r= eward for it.
