Currently beta versions of both SLES 15 SP3 and openSUSE 15.3 are available for broader testing. In doing so I stumbled over a nasty bug in Autoyast, SUSE’s solution for automatic OS installations, when using the rules.xml mechanism:
I like fresh, reproducible installs when a new version of your preferred Linux distro (in my case openSUSE) comes out. Ensuring the perceived (!) feeling that a system is a “clean” state is hard enough during its lifecycle already and ensuring it is so after doing an upgrade installation is even harder. That’s why I… Continue reading Introducing a custom Yast module for importing libvirt configuration files from existing installations
I don’t know yet if it’s really a bug or not but I’ve seen some weird behavior while trying to programmatically set up a VM in EFI mode with libvirt which involves a blank VM console unless I explicitly disable suspend-to-mem for the EFI firmware.
The enterprise world is one that is fond of funny, crappy hardware gadgets such as KVM (Keyboard-Video-Mouse) switches, often in the matrix variant: you have one or more consoles connected matrix-style to different computers, for the obvious benefit of not having to connect keyboard, mouse and monitor when needed let alone have a set connected… Continue reading Why your kernel’s drm.edid_firmware parameter doesn’t work anymore in libvirt environments
Getting your custom OS installation ISO to boot from both DVDs and USB sticks is but the first step in making the whole installation working from USB sticks as well. There can still be unexpected pitfalls in the course of the installation process as I encountered yesterday and while my experience was with a specific… Continue reading Consistent udev storage names during and after OS installation: when minimal is too minimal
This may seem to some of you like a blast from a long forgotten past but that’s what an Enterprise world often looks like: I’ve been seeing scripting that creates a custom Linux installation ISO from given public images, adds extra software repositories, install automation, provisioning for delegating to a dedicated config management tool (Puppet,… Continue reading Recreating ISOs that boot from both DVD and mass storage such as USB sticks and in both legacy BIOS and UEFI environments
Here’s another tip related to AutoYast and scripts such as pre-install scripts, indirectly related to the previous post on error reporting.
After the opener on Retaining/reusing existing partitions and the followup on Partitioning that works on both real hardware and inside virtual machines, this post looks at error reporting in pre-install scripts.
Continuing a small series on Autoyast tips and tricks after the first post, Retaining/Reusing existing partitions, let’s look at another use case for dynamically modifying the Autoyast profile.
If you plan to do automated installs of openSUSE or SUSE Linux Enterprise Server (SLES), you will sooner or later meet their installation automation solution, Autoyast. Since there is not much info on the Web on Autoyast control files and scripts apart from the official documentation, I thought I could contribute some of my own… Continue reading Autoyast: Retaining/reusing existing partitions
