Debian bullseye: changes in util-linux #newinbullseye

Monday, July 5th, 2021

Continuing with #newinbullseye. One package that isn’t new but its tools are used by many of us is util-linux, providing many essential system utilities. There is util-linux v2.33.1 in Debian/buster and util-linux v2.36.1 in Debian/bullseye, and as usual there are many new features and options available. I don’t want to replicate the release notes provided […]

efivars is gone with Debian/bullseye #newinbullseye

Wednesday, June 9th, 2021

Continuing with #newinbullseye, it’s worth being aware of, that efivars is gone with the kernel version shipped as of Debian/bullseye. Quoting from wiki.debian.org/UEFI: The Linux kernel gives access to the UEFI configuration variables via a set of files under /sys, using two different interfaces. The older interface was showing files under /sys/firmware/efi/vars, and this is […]

Thursday, May 27th, 2021

Debian v11 with codename bullseye is supposed to be released as new stable release soon-ish (let’s hope for June, 2021! :)). Similar to what we had with #newinbuster and previous releases, now it’s time for #newinbullseye! I was the driving force at several of my customers to be well prepared for bullseye before its freeze, […]

How to properly use 3rd party Debian repository signing keys with apt

Tuesday, February 16th, 2021

(Blogging this, since this is a recurring anti-pattern I noticed at several customers and often comes up during deployments of 3rd party repositories.) Update on 2021-02-19: clarified, that Signed-By requires apt >= 1.1, thanks Vincent Bernat Many upstream projects provide Debian repository instructions like this: curl -fsSL https://example.com/stable/debian.gpg | sudo apt-key add – Do not […]

Some useful bits about Linux hardware support and patched Kernel packages

Wednesday, July 31st, 2019

Disclaimer: I started writing this blog post in May 2018, when Debian/stretch was the current stable release of Debian, but published this article in August 2019, so please keep the version information (Debian releases + kernels not being up2date) in mind. The kernel version of Debian/stretch (4.9.0) didn’t support the RAID controller as present in […]

Inception: VM inside Docker inside KVM – Testing Debian VM installation builds on Travis CI

Wednesday, July 25th, 2018

Back in 2006 I started to write a tool called grml-debootstrap. grml-debootstrap is a wrapper around debootstrap for installing Debian systems. Using grml-debootstrap, it’s possible to install Debian systems from the command line, without having to boot a Debian installer ISO. This is very handy when you’re running a live system (like Grml or Tails) […]

We’re coming closer to the Debian/stretch stable release and similar to what we had with #newinwheezy and #newinjessie it’s time for #newinstretch! Hideki Yamane already started the game by blogging about GitHub’s Icon font, fonts-octicons and Arturo Borrero Gonzalez wrote a nice article about nftables in Debian/stretch. One package that isn’t new but its tools […]

Continuing the #newinjessie game: Bernhard Miklautz, contributor to jenkins-debian-glue and author of jenkins-package-builder (being in an early stage but under active development to provide support for building RPMs, similar to what jenkins-debian-glue provides for building Debian/Ubuntu packages) pointed out that there are new tools related to RPM packaging available in Debian/jessie: mock: Build rpm packages […]

I wasn’t sure whether I would make it to Linuxdays Graz (GLT15) this year so I didn’t participate in its call for lectures.

Grml was initially started by myself in 2003 – I registered the domain on September 16, 2003 (so technically it would be 11 years already :)). It started with a […]

How geeks celebrate a birthday AKA bin2dec

Thursday, August 30th, 2012

Far away from Rosetta Code, but that’s what Frank and I came up with when explaining 100000₂: Guile: guile <<< \#b100000 guile -c ‘((@@ (ice-9 format) format) #t “~d~%” #b100000)’ Racket: racket -e ‘#b100000’ Ruby: ruby -e ‘puts “100000”.to_i(2)’ Python: python -c ‘print int(“100000”, 2)’ Perl: perl -e ‘print 0b100000’ Zsh: zsh -c ‘print $((2#100000))’ […]
