fidzu : debian

I sometimes use Vagrant to deploy my VM&aposs and recently when I tried to deploy one for Trixie, I could see one available. So I checked the official Debian images on Vagrant cloud at https://portal.cloud.hashicorp.com/vagrant/discover/debian and could not find an image for trixie on Vagrant cloud.

Also looked at other cloud image sources like Docker hub, and I could see an image their for Trixie. So I looked into how I can generate a Vagrant image locally for Debian to use.

make install-build-deps

Searched on Salsa and stumbled upon https://salsa.debian.org/cloud-team/debian-vagrant-images

Cloned the repo from salsa

$ git clone https://salsa.debian.org/cloud-team/debian-vagrant-images.git

Install the build dependencies

$ make install-build-deps

this will install some dependency packages, will ask for sudo password if need to install something not already installed.

Let&aposs call make help

$ make help
To run this makefile, run:
   make <DIST>-<CLOUD>-<ARCH>
  WHERE <DIST> is bullseye, buster, stretch, sid or testing
    And <CLOUD> is azure, ec2, gce, generic, genericcloud, nocloud, vagrant, vagrantcontrib
    And <ARCH> is amd64, arm64, ppc64el
Set DESTDIR= to write images to given directory.

$ make trixie-vagrant-amd64
umask 022; \
./bin/debian-cloud-images build \
  trixie vagrant amd64 \
  --build-id vagrant-cloud-images-master \
  --build-type official
usage: debian-cloud-images build
debian-cloud-images build: error: argument RELEASE: invalid value: trixie
make: *** [Makefile:22: trixie-vagrant-amd64] Error 2

As you can see, trixie is not even in the available options and it is not building as well. Before trying to look at updating the codebase, I looked at the pending MR&aposs on Salsa and found Michael Ablassmeier&aposs pending merge request at https://salsa.debian.org/cloud-team/debian-vagrant-images/-/merge_requests/18

So let me test that commit and see if I can build trixie locally from Michael&aposs MR

$ git clone https://salsa.debian.org/debian/debian-vagrant-images.git

$ cd debian-vagrant-images/

$ git checkout 8975eb0 #the commit id of MR 

Now let&aposs see if we can build trixie now

$ make help
To run this makefile, run:
   make <DIST>-<CLOUD>-<ARCH>

Although we can now build the images, we just don&apost see an option for it in the help text, not even for bookworm. Just the text in Makefile is outdated, but I can build and trixie Vagrant box now. Thanks to Michael for the fix.

Somehow along the way, a feature that I've had across DOS, OS/2, FreeBSD, and Linux - and has been present on PCs for more than 40 years - is gone.

That feature, of course, is the 80×25 text console.

Linux has, for awhile now, rendered its text console using graphic modes. You can read all about it here. This has been necessary because only PCs really had the 80×25 text mode (Raspberry Pis, for instance, never did), and even they don't have it when booted with UEFI.

I've lately been annoyed that:

• The console is a different size on every screen - both in terms of size of letters and the dimensions of it
• If a given machine has more than one display, one or both of them will have parts of the console chopped off
• My system seems to run with three different resolutions or fonts at different points of the boot process. One during the initrd, and two different ones during the remaining boot.

And, I wanted to run some software on the console that was designed with 80×25 in mind. And I'd like to be able to plug in an old VGA monitor and have it just work if I want to do that.

That shouldn't be so hard, right? Well, the old vga= option that you are used to doesn't work when you booted from UEFI or on non-x86 platforms. Most of the tricks you see online for changing resolutions, etc., are no longer relevant. And things like setting a resolution with GRUB are useless for systems that don't use GRUB (including ARM).

VGA text mode uses 8×16 glyphs in 9×16 cells, where the pixels are non-square, giving a native resolution of 720×400 (which historically ran at 70Hz), which should have streched pixels to make a 4:3 image.

While it is possible to select a console font, and 8×16 fonts are present and supported in Linux, it appears to be impossible to have a standard way to set 720×400 so that they present in a reasonable size, at the correct aspect ratio, with 80×25.

Tricks like nomodeset no longer work on UEFI or ARM systems. It's possible that kmscon or something like it may help, but I'm not even certain of that (video=eDP1:720×400 produced an error saying that 720×400 wasn't a supported mode, so I'm unsure kmscon would be any better.) Not that it matters; all the kmscon options to select a font or zoom are broken, and it doesn't offer mode selection anyhow.

I think I'm going to have to track down an old machine.

Sigh.

If you use HaProxy to e.g. terminate TLS on the frontend and connect via TLS to a backend, one has to take care of sending the SNI (server name indication) extension in the TLS handshake sort of manually.

Even if you use host names to address the backend server, e.g.

server foobar foobar.example:2342 ssl verify required ca-file /etc/haproxy/ca/foo.crt

HaProxy will try to establish the connection without SNI. You manually have to enforce SNI here, e.g.

server foobar foobar.example:2342 ssl verify required ca-file /etc/haproxy/ca/foo.crt sni str(foobar.example)

The surprising thing here was that it requires an expression, so you can not just write sni foobar.example, you've to wrap it in an expression. The simplest one is making sure it's a string.
