{snipped stuff about CAM and mps and ZFS deadman}
Jeremy, I have a question about enabling kernel dumps based on my
current swap config.
I currently have a 1TB drive split into 4 geli encrypted swap
partitions (Freebsd doesn't like swap partitions over ~250 GB and I
have lots of RAM).
These partitions are UFS-swap partitions and are
not backed by any mirroing or ZFSing.
So, how do I best enable crash dumps? If I need to remove encryption,
I can do that.
I have zero familiarity with geli(8), gbde(8), and file-based swap.
My gut feeling is that you cannot use this to achieve a proper kernel
panic dump, but I have not tried it.
You can force a kernel panic via sysctl debug.kdb.panic=1. I'm not
sure if an automatic memory dump to swap happens with the stock GENERIC
kernel however. I can talk more about that if needed (it involves
adding some options to your kernel config, and one rc.conf variable).
Regarding enabling crash dumps as a general concept:
In rc.conf you need to have dumpdev=auto (or point it to a specific
disk slice, but auto works just fine assuming you have a swap or
dump device defines in /etc/fstab -- see savecore(8) man page). Full
details are in rc.conf(5). How this works:
After a system reboots, during rc script startup, rc.d/savecore runs
savecore which examines the configured dumpdev for headers + tries to
detect if there was previously a kernel panic. If it finds one, it
begins pulling the data out of swap and writing the results directly to
/var/crash in a series of files (again, see savecore(8)). It does this
***before*** swapon(8) is run (reason why should be obvious) via
rc.d/swapon. After it finishes, swapon is run (meaning anything
previously written to the swap slice is effectively lost), and the
system continues through the rest of the rc scripts.
Purely for educational purposes: to examine system rc script order, see
rcorder(8) or run rcorder /etc/rc.d/*.

Fourth Generation, no less! +1 Thank you Ian for cross-posting here. The first thing I did when I got the new chapter for review was search for the work EzJail and I was curious as to why EzJail is not mentioned anywhere in this new proposal and why it isn't mentioned in the current handbook either under in section 16.5.2 High-Level Administrative Tools in the FreeBSD Ports Collection. If there is __any__ tool that should be mentioned in the jails chapter it is EzJail because it's really easy to use and does a damn good job. We've been using it in production __extensively__ since about 2010 and the one and only issue we've had was probably related to some sort of border-line bug with nullfs which has never happened since. We currently run half a dozen servers with anywhere from 12 to 24 jails each and we've only had a single isolated incident and it wasn't even related directly to EzJail. We use flavours extensively and constantly derive jails from others and move jails between servers, much like if we were using VMWare; it's that easy, or easier, and works every time. NOW some things start to make sense to me, when I posted a problem with EzJail here last year that very few people, if any, knew what I was talking about. An how could they? if it's not mentioned anywhere in the handbook or that jail man page(s). In fact, looking back at this thread[1] I can see that great deal of misunderstanding an unnecessary confusion could have been that the term EzJail meant nothing to most people commenting on the thread. When I commented the problem to Dirk he immediately recognized that it could have been a problem with nullfs and so did jb[2], who not only immediately thought of nulls, but actually found some bugs that were very similar to my situation[3], and which is BTW still open AFAICT. Anyway, the point I'm trying to make is that it seems quite odd that EzJail is not very publicized and I would like to see it prominently mentioned in the handbook and man pages as a great tool for Jail administration.

Installing openssl from ports
Hi, I understand that heimdal and openssl are both port of the base system and both install fine with a system build/install. But when I attempt to install the latest openssl for the port system, it fails with a conflict (installs file in the same place) with heimdal. I've search the web for an answer but haven't found one and asked the port owner. So my question is short of editing the Make file to remove the installation of the file in conflict, what do I need to do to install the openssl port?

You need to put this in your /etc/make.conf file sans quotations marks: WITH_OPENSSL_PORT=yes and then build the port. Be sure to run make config in the port prior to actually building it and that is about it. If you are building it manually, you might want to run make clean in the port prior to attempting to build it though. -- Jerry ♔ Disclaimer: off-list followups get on-list replies or get ignored.
