Gemini Capsule in a FreeBSD Jail

With the recent release of FreeBSD 13, I wanted to test it out on a spare RaspberryPi 3 that was part of my old Kubernetes cluster.
In particular, FreeBSD Jails have always interested me, although I’ve never used them in practice. Over the years I’ve managed operating system virtualization through Solaris Zones and Docker containers, and Jails seem like and good middle ground between the two - easier to manage than zones and closer to the OS than Docker.
I also want to run my own Gemini capsule locally to use some of the features that my other hosted capsules don’t have (like SCGI/CGI) and setting up a capsule in a Jail is a good way to learn both at the same time.

NetBSD VM on bhyve (on TrueNAS)

My new NAS at home is running TrueNAS Core. So far, it has been excellent, however I struggled a bit setting up a NetBSD VM on it. Part of the problem is that a lot of the docs and how-tos I found are stale, and the information in it no longer applies.
TrueNAS Core allows running VMs using bhyve, which is FreeBSD’s hypervisor. NetBSD is not an officially supported OS, at least according to the guest OS chooser in the TrueNAS web UI :) But since the release of NetBSD 9 a while ago, things have become far simpler than they used to be – with one caveat (see below).

Migrating drives and the zpool from one host to another.

Today is the day.

Today I move a zpool from an R710 into an R720. The goal: all services on that zpool start running on the new host.

Fortunately, that zpool is dedicated to jails, more or less. I have done some planning about this, including moving a poudriere on the R710 into a jail.

Now it is almost noon on Saturday, I am sitting in the basement (just outside the server room), and I’m typing this up.

• In this post:

  • FreeBSD 12.0
  • Dell R710 (r710-01)
  • Dell R720 (r720-01)
  • drive caddies from eBay and now I know the difference between SATA and SATAu

OpenBSD in 2019

I’ve used OpenBSD on and off since 2.1. More back then than in the last 10 years or so though, so I thought I’d try it again.

What triggered this was me finding a silly bug in GNU cpio that has existed with a “FIXME” comment since at least 1994. I checked OpenBSD to see if it had a related bug, but as expected no it was just fine.

I don’t quite remember why I stopped using OpenBSD for servers, but I do remember filesystem corruption on “unexpected power disconnections” (even with softdep turned on), which I’ve never really seen on Linux.

That and that fewer things “just worked” than with Linux, which matters more when I installed more random things than I do now. I’ve become a lot more minimalist. Probably due to less spare time. Life is better when you don’t run things like PHP (not that OpenBSD doesn’t support PHP, just an example) or your own email server with various antispam tooling, and other things.

This is all experience from running OpenBSD on a server. On my next laptop I intend to try running OpenBSD on the dektop, and will see if that more ad-hoc environment works well. E.g. will gnuradio work? Lack of other-OS VM support may be a problem.

• Verdict

Ouch, that’s a long list of bad stuff. Still, I like it. I’ll continue to run it, and will make sure my stuff continues working on OpenBSD.

And maybe in a year I’ll have a review of OpenBSD on a laptop.

Batch renaming images, including image resolution, with awk

The most recent item on my list of “Geeky things I did that made me feel pretty awesome” is an hour’s adventure that culminated in this code:

$ file IMG* | awk 'BEGIN{a=0} {print substr($1, 1, length($1)-5),a++"_"substr($8,1, length($8)-1)}' | while read fn fr; do echo $(rename -v "s/$fn/img_$fr/g" *); done

I hate the X11 ICCCM selection system, and you should too - A Rant

d00d, that document is devilspawn. I've recently spent my nights in pain
implementing the selection mechanism. WHY OH WHY OH WHY? why me? why did I choose to do this? and what sick evil twisted mind wrote this damn spec? I don't know why I'm working with it, I just wanted to make a useful program.

I didn't know what I was getting myself in to. Nobody knows until they try it. And once you start, you're unable to stop. You can't stop, if you stop then you haven't completed it to spec. You can't fail on this, it's just a few pages of text, how can that be so hard? So what if they use Atoms for everything. So what if there's no explicit correlation between the target type of a SelectionNotify event and the type of the property it indicates?

So what if the distinction is ambiguous? So what if the document is littered with such atrocities? It's not the spec's fault, the spec is authoritative. It's obviously YOUR (the implementor's) fault for misunderstanding it. If you didn't misunderstand it, you wouldn't be here complaining about it would you?

HAMMER2 emergency space mode

As anyone who has been running HAMMER1 or HAMMER2 has noticed, snapshots and copy on write and infinite history can eat a lot of disk space, even if the actual file volume isn’t changing much. There’s now an ‘emergency mode‘ for HAMMER2, where disk operations can happen even if there isn’t space for the normal history activity. It’s dangerous, in that the normal protections against data loss if power is cut go away, and snapshots created while in this mode will be mangled. So definitely don’t leave it on!
