My own take: 1) I really don't see the Handbook as all that great. It's great that a volunteer team put it together, but when I compare it to https://access.redhat.com/knowledge/docs/Red_Hat_Enterprise_Linux/ or http://download.oracle.com/docs/cd/E19963-01/index.html, I don't think the FreeBSD handbook compares well. 2) Lack of geek-on-the-street support. If I'm looking for an experienced Linux administrator, I'll get thousands of applications; for a Solaris administrator, I'll get hundreds. For a BSD admin? Maybe half a dozen? 3) Updates are a mess. It's cool that I *can* compile a new kernel, but that I *have* to is ridiculous. Updating a server should not be more difficult than yum update -- full stop. 4) Poor support from running FreeBSD under virtualization. When I start to think about deploying a new server, I'll generally spin up a new VM on my workstation or on an ESXi host. If I have trouble with that VM, my first response is not going to be to try again with the same OS, it's going to be to fall back to a configuration I know works. There are some things I liked a lot about FreeBSD -- its support for DTrace and ZFS was the reason I looked into it in the first place. But from where I sit, technologies like that are just duct-taped on to the base system rather than integrated. (For example, why isn't there something like the [Open]Solaris beadm, where the system creates a ZFS snapshot automatically before any major updates to let you revert to not just an earlier kernel but an earlier world?) Just my $.02. -- Dave Pooser Cat-Herder-in-Chief, Pooserville.com ...Life is not a journey to the grave with the intention of arriving safely in one pretty and well-preserved piece, but to slide across the finish line broadside, thoroughly used up, worn out, leaking oil, and shouting GERONIMO!!! -- Bill McKenna ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

This is the most important one, because all technical problems are just won't get solved because are even not viewed as problems. The FreeBSD Project does not listen to users' needs. The typical response when poor user want something is: we don't need this, we won't change for you, with where are your patches? at best. Then many users go out when see such attitude toward them. The key points are: 1) *The competent user is not zealot*. 2) The system is *for users, not for developers*. === I probably would have been wiser not to respond to this thread at all; once the OP threw the bait out there people were bound to get angry and defensive.

Ongoing JRE support in FreeBSD?
I'm planning on setting up a machine to run a Java server app, and the OS candidates are CentOS or FreeBSD. I'd prefer FreeBSD, for reasons mostly involving ZFS and DTrace, but when I go to http://www.freebsd.org/java I notice that the binaries are certified with 6.x/7.x and the last entry in Newsflash is posted July 10 of 2010. This does not, on the surface, appear to be a vibrant and active project. That said, I see there are packages in the 8.2 RELEASE tree, so there's clearly some kind of work going on. I guess my question is, can I expect FreeBSD to be a solid platform for Java deployment going forward, or am I better off taking the road more traveled and deploying on Linux? -- Dave Pooser Cat-Herder-in-Chief, Pooserville.com Pulling together is the aim of despotism and tyranny.

PostgreSQL + 8.1 RELEASE + DTrace = pain?
First off, I'll freely admit I'm a *BSD noob; I've been administering Mac servers for a decade and OpenSolaris and Linux for 3-4 years but this is my first ever attempt to set up a FreeBSD system. The goal is to replace a Linux box that is currently a PostgreSQL database server; I need LDAP authentication and I want DTrace. (I also want GSSAPI, but that's another discussion entirely). (Why FreeBSD? DTrace and ZFS without the Oracle Solaris pricetag. Plus it's a *NIX I haven't used yet.) So I used csup to update to the latest ports, built postgresql90-server from ports with LDAP and no DTrace, and it worked fine. Then I used pkg_delete to remove the postgresql packages (server and client), recompiled the kernel to include DTrace and eliminate some unused drivers, updated loader.conf to bring up dtraceall at boot, did a make clean and a make config to add DTrace, and built postgresql90-server again. It appeared to work fine, but now I'm getting segfaults when I try to launch it. Am I doing something obviously stupid here? Is there a good source for troubleshooting steps? What other information should I be posting to help y'all help me figure this out? -- Dave Pooser Cat-Herder-in-Chief, Pooserville.com ...Life is not a journey to the grave with the intention of arriving safely in one pretty and well-preserved piece, but to slide across the finish line broadside, thoroughly used up, worn out, leaking oil, and shouting GERONIMO!!! -- Bill McKenna ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
