Anybody got an idea what's going on?
When I checked online, rpilocator.com doesn't even
mention the Pi2 and Amazon had only one, for ~150$.
Pi3 seems more available but even more expensive.
Raspberrypi.com claims the Pi2 will be in production
till 2026, but that looks like wishful thinking.

Well you can back-order them for expected delivery at the end of
2023, so somebody believes they'll be back eventually: https://www.newark.com/raspberry-pi/rpi2-modb-v1-2/sbc-raspberry-pi-2-model-b-v1/dp/54AJ2909

Nothing much different to every other RPi model based on that
website where most of the other models are on back-order for 2023
or later as well (Farnell have some more options in the UK,
including Pi 1 Model Bs for delivery before the end of the year).

The Pi2 originally had its own chip (BCM2836) - with quad core Cortex A7. When the Pi3 was launched the Pi2 was relaunched as v1.2 with a slower version of the same chip as the Pi3 (BCM2837, quad core 64-bit A53). That prevented them having to keep manufacturing the 2836 silicon. It then
became just a niche version of the Pi3.
While it's technically still in production, the only people who want it are industrial folks who have some dependency on the particular Pi2 shape or the A7. They have their own channels to buy it in volume - for the rest of us the Pi3 is effectively the same hardware but faster and more widely available.
You may find that FreeBSD needs updating, though, if you're still running an old kernel that doesn't know about the Pi3.
I've two Pi3's, and aarch64 is a _very_ tight fit unless it's a binary-only install.

I don't get it, do you mean space? Just get a bigger sd card, obviously.

No, RAM. With 4 GB it would be ok. Self-hosting takes a lot of RAM when building LLVM. Swap helps, but then USB becomes a narrow bottleneck.
For a binary only installation it isn't an issue, but I've been in the
habit of self-hosting on my servers.
Anybody got an idea what's going on? At this point
a Pi4 kit is vast overkill for the job but looks
like the most available option. I'm using FreeBSD
to run BIND9 for an authoritative nameserver. No
display or keyboard, just storage, wired ethernet
and serial console.

Just the other day, I scored a Compute Module 4 when pishop.us got a few hundred of them in. Price is about the same as a comparable Raspberry Pi 4, they're available with onboard eMMC storage (no SD card needed), and there's a wide variety of carrier boards that bring out whatever I/O is needed.

Just how much extra hardware is required to make a CM4 a stand-alone host?

It depends on what you want to do. The official I/O board brings out lots
of extra I/O, including things like PCI Express that aren't available from the RPi 4 without hacking it, but is a fair bit larger. At the other
extreme are boards barely large enough for a GPIO header and one of those 100-pin connectors the CM4 uses. There are even some that adapt the CM4
into the normal Raspberry Pi form factor, making it somewhat of a drop-in replacement. There are also other companies adopting the CM4 form factor to roll out boards with other SOCs that can use the same ecosystem of add-ons.
For my 3D printer OctoPrint hosts, I'm using the Waveshare Nano Base Board
A:
https://www.pishop.us/product/nano-base-board-a-for-raspberry-pi-compute-module-4/
It breaks out a USB 2.0 port, MicroSD slot (not used if the CM4 has eMMC), camera, and GPIO, and uses USB-C for power. Of those, I only need four GPIO pins (power and UART) to connect to a printer running Marlin. This board is the same size as the CM4.
I also have a router built around a CM4, running OpenWRT. That one uses the DFRobot IoT Router Carrier Board Mini:
https://www.dfrobot.com/product-2242.html
It provides two Gigabit Ethernet ports (one built-in to the SOC, one as an add-on over PCI Express), a MicroSD slot, a 26-pin GPIO header, and two
USB-C ports (one for power, one (2.0) for data). This board is a little bit larger, but the total system size still easily fits in your hand.
Neither of these include HDMI because I don't need it for the intended applications.
I'd probably want all but HDMI. From the pricing it appears that a CM4 + I/O combo will cost somewhat more than a standard Pi4, other things being equal.
Some sort of enclosure would also be helpful, but I didn't see any in a cursory search.
