Last 2 posts on the topic that I've seen (Sep. 23, 2013): http://lists.freebsd.org/pipermail/freebsd-hackers/2013-September/043429.ht= ml http://lists.freebsd.org/pipermail/freebsd-hackers/2013-September/043442.ht= ml > 2. I'm assuming jails still exist in FreeBSD (I haven=92t used BSD in a l= ong > time), how do they relate, or fit in, with VPS and Bhyve offerings? >=20 Yes. Changed slightly -- you configure jails in /etc/jail.conf now. Jails are enhanced by VPS and Bhyve offerings (which, the best of my knowle= dge, require jails).

Is LZ4 the default compression mode? >=20 At $work we're actively deploying ZFS into production. It's very stable from our testing over several years. Mileage seems to depend on configuration complexity, but overall is extremely stable. The default zpool version is 28, but if you do a "zpool upgrade ..." you'll= then jump to the new 5000 version introduces "zfs feature flags". > 8.

Any work on > rollback with ZFS? >=20 For better ports management, you could look into poudriere. There's a tutor= ial on bsdnow.tv The idea is that you'll use poudriere to intelligently manage the ports you= want to roll binary packages. Then on 10 with the new `pkg' framework (formerly = known as PkgNg) those binary packages are intelligently applied. As for self-contained packages... I believe you want what is known as PBIs. However, I think only PC-BSD offers PBIs -- I don't think they are offered = in FreeBSD 10 by default (maybe there's a way though). I assume what you mean by "rollback with ZFS" is... "boot loader integratio= n with BEs so you can boot to a previous snapshot". Look for that in 10.1. > 9. I recall device support being a large hurtle for me in the past. How f= ar > behind is driver development relative to Linux, for server equipment?

Knowing what kind of hardware you use would help answer the question better. We've been very happy with LSI MegaRAID/SAS support, Broadcom 10G iSCSI support, QLogic 8G FC support, and many many more. As for FreeBSD-world with Linux-kernel... that sounds like the exact opposi= te of the Debian kFreeBSD project (FreeBSD-kernel, Linux-world). I don't suppose there's much demand in that. People that want such a thing seem to be quite happy with ArchLinux -- which uses a BSD-style init framew= ork. There's also ArchBSD and ArchHurd. > 10. How is the Java ecosystem on FreeBSD? >=20 Well, daiblo-jdk is dead, long live OpenJDK? Seems to be the motions around here at $work. > I haven=92t used FreeBSD in ages.
