Wayland in Bookworm

We are getting towards the freeze for Debian/Bookworm so the current state of packages isn’t going to change much before the release. Bugs will get fixed but missing features will mostly be missing until the next release.

Anarcat wrote an excellent blog post about using Wayland with the Sway window manager [1]. It seems pretty […]

KDE Icons Disappearing in Debian/Unstable

One of my workstations is running Debian/Unstable with KDE and SDDM on an AMD Radeon R7 260X video card. Recently it stopped displaying things correctly after a reboot, all the icons failed to display as well as many of the Qt controls. When I ran a KDE application from the command line I got the […]

BTRFS and SE Linux

I’ve had problems with systems running SE Linux on BTRFS losing the XATTRs used for storing the SE Linux file labels after a power outage.

Here is the link to the patch that fixes this [1]. Thanks to Hans van Kranenburg and Holger Hoffstätte for the information about this patch which was already included in […]

WordPress Multisite on Debian

WordPress (a common CMS for blogs) is designed to be copied to a directory that Apache can serve and run by a user with no particular privileges while managing installation of it’s own updates and plugins. Debian is designed around the idea of the package management system controlling everything on behalf of a sysadmin.

When […]

Apache Mesos on Debian

I decided to try packaging Mesos for Debian/Stretch. I had a spare system with a i7-930 CPU, 48G of RAM, and SSDs to use for building. The i7-930 isn’t really fast by today’s standards, but 48G of RAM and SSD storage mean that overall it’s a decent build system – faster than most systems I […]

More KVM Modules Configuration

Last year I blogged about blacklisting a video driver so that KVM virtual machines didn’t go into graphics mode [1]. Now I’ve been working on some other things to make virtual machines run better.

I use the same initramfs for the physical hardware as for the virtual machines. So I need to remove modules that […]

SE Linux in Debian/Stretch

Debian/Stretch has been frozen. Before the freeze I got almost all the bugs in policy fixed, both bugs reported in the Debian BTS and bugs that I know about. This is going to be one of the best Debian releases for SE Linux ever.

Systemd with SE Linux is working nicely. The support isn’t as […]

802.1x Authentication on Debian

I recently had to setup some Linux workstations with 802.1x authentication (described as “Ethernet authentication”) to connect to a smart switch. The most useful web site I found was the Ubuntu help site about 802.1x Authentication [1]. But it didn’t describe exactly what I needed so I’m writing a more concise explanation.

The first thing […]

LUV Server Upgrade to Jessie

On Sunday night I started the process of upgrading the LUV server to Debian/Jessie from Debian/Wheezy. My initial plan was to just upgrade Apache first but dependencies required upgrading systemd too.

One problem I’ve encountered in the past is that the Wheezy version of systemd will often hang on an upgrade to a newer version. […]

BTRFS Status June 2015

The version of btrfs-tools in Debian/Jessie is incapable of creating a filesystem that can be mounted by the kernel in Debian/Wheezy. If you want to use a BTRFS filesystem on Jessie and Wheezy (which isn’t uncommon with removable devices) the only options are to use the Wheezy version of mkfs.btrfs or to use a Jessie […]
