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 […]

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 […]

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, […]

(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 […]

We did it again™, at the end of June we released Grml 2020.06, codename Ausgehfuahangl. This Grml release (a Linux live system for system administrators) is based on Debian/testing (AKA bullseye) and provides current software packages as of June, incorporates up to date hardware support and fixes known issues from previous Grml releases. I am […]

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 […]

Debian buster is there, and similar to what we had with #newinwheezy, #newinjessie and #newinstretch it’s time for #newinbuster! One package that isn’t new but its tools are used by many of us is coreutils, providing many essential system utilities. We have coreutils v8.26-3 in Debian/stretch and coreutils v8.30-3 in Debian/buster. Compared to the changes […]

Debian buster is there, and similar to what we had with #newinwheezy, #newinjessie and #newinstretch it’s time for #newinbuster! Update on 2019-07-26 22:55 UTC: Cyril Brulebois pointed out, that findmnt (find a filesystem) was available in Debian/stretch already as part of the mount package, updated the blog post accordingly One package that isn’t new but […]

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 […]

At DebConf 16 I was working on a systemd backport for Debian/jessie. Results are officially available via the Debian archive now. In Debian jessie we have systemd v215 (which originally dates back to 2014-07-03 upstream-wise, plus changes + fixes from pkg-systemd folks of course). Now via Debian backports you have the option to update systemd […]

mur.strom ist ein Podcast aus Graz rund um Technologie und Gesellschaft. Am 6. Jänner wurde eine neue Folge veröffentlicht, in der es um das Debian-Projekt geht. Sebastian Ramacher und ich waren die Interview-Gäste, viel Spaß beim Hören der ~1h 43 Minuten: http://murstrom.at/msp016-debian/

At the Debian Conference 2015 I gave a talk about Continuous Delivery of Debian packages. My slides are available online (PDF, 753KB). Thanks to the fantastic video team there’s also a recording of the talk available: WebM (471MB) and on YouTube.

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. But when meeting folks on the evening before the main event I came up with the idea of giving a lightning talk as special kind of celebrating the Debian jessie release. So […]

Repeating what I did for the last Debian release with the #newinwheezy game it’s time for the #newinjessie game: Debian/jessie AKA Debian 8.0 includes a bunch of packages for people interested in digital forensics. The packages maintained within the Debian Forensics team which are new in the Debian/jessie stable release as compared to Debian/wheezy (and […]

On 22nd of October 2004 an event called OS04 took place in Seifenfabrik Graz/Austria and it marked the first official release of the Grml project. 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 […]

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))’ […]

jenkins-debian-glue is an open source project of mine which recently celebrated its first birthday and it’s time to finally write about it. jenkins-debian-glue allows you to build Debian and Ubuntu packages directly from the Jenkins continuous integration system. It retrieves package sources from a version control repository, adjusts debian/changelog (handle version number + mention changes […]
