openSUSE:Standards Rpm Metadata – openSUSE: Repository layout

Posted by jpluimers on 2020/07/09

For my link archive: [WayBack] openSUSE:Standards Rpm Metadata – openSUSE: Repository layout.

It is not fully up to date any more on primary.xml.gz, so here are my notes for the aarch64 version of Tumbleweed:

  1. Inspect http://download.opensuse.org/ports/aarch64/tumbleweed/repo/oss/repodata/repomd.xml [WayBack] for the name of *-primary.xml.gz (in this case http://download.opensuse.org/ports/aarch64/tumbleweed/repo/oss/repodata/d701c298b21d0b995c9560f9cfcc84685cb916deacc4f4c4a613a9b9d8f5aa57-primary.xml.gz [WayBack]
  2. Download that .gz file and uncompress it
  3. Inspect the *-primary.xml from it, look inside the metatadata root element for a package having a name element with value openSUSE-release: that package element now has a version element having a ver attribute containing the version text.

Raspberry Pi, Tumbleweed, btrfs

Posted by jpluimers on 2020/06/15

I want to use btrfs as filesystem on a Raspberry Pi with opensuse Tumbleweed.

It is hard to find out how, so here are a few links that should help me from “opensuse” “tumbleweed” “btrfs” “raspberry” pi:

Raspberry Pi 1B OpenSuSE Tumbleweed zypper upgrade problem · GitHub

Posted by jpluimers on 2020/05/25

It looks like OpenSuSE has stopped supporting Raspberry Pi 1, so the best likely is to recycle it into a Pi-Hole as basically it’s been dead since mid 2017: [WayBack] Raspberry Pi 1B OpenSuSE Tumbleweed zypper upgrade problem · GitHub.

Build status for armv6l support: [WayBack] Project openSUSE:Factory:ARM Status Monitor – openSUSE Build Service

ipmi – Linux: Why does Single User mode work on Serial Console but not on the attached Keyboard/Video/Monitor? – Server Fault

Posted by jpluimers on 2020/05/19

From [WayBack] ipmi – Linux: Why does Single User mode work on Serial Console but not on the attached Keyboard/Video/Monitor? – Server Fault (slightly edited; thanks Patrick!):

Because init has not spawned off multiple TTYs yet (getty, mgetty, etc), so you only have the primary TTY. The primary TTY is the last console= parameter on the kernel command line. All the console parameters get the output, but only the last one will be able to act as input.

Show openSUSE:Factory / bootchart – openSUSE Build Service

Posted by jpluimers on 2020/05/15

On my research list: [WayBack] Show openSUSE:Factory / bootchart – openSUSE Build Service.

I bumped here when researching on how to list services: [WayBack] init.d – Command to list services that start on startup? – Ask Ubuntu

It seems few people use it on opensuse, but it is interesting for analysing the boot process nonetheless.

I already found out this is in fact bootchart2: [WayBack] GitHub – xrmx/bootchart: merge of bootchart-collector and pybootchartgui

Some links that should help me further are these:

From the last link, this translation:

A. systemd-analyze

You will see the total computer startup time after:

systemd-analyze

A complete list of how much each individual service has taken is when you complete:

systemd-analyze blame

You will see the most problematic processes after you complete:

systemd-analyze critical-chain

You can create a picture:

systemd-analyze plot> /tmp/systemd-analyze.svg

Suitable for: openSUSE 11.4, 12.x, 13.1, Leap 42.x

Not suitable: openSUSE 13.2

B. bootchart

First, install the bootchart package (bootchart 2 version of the program). If you are using openSUSE Leap 42.x or later, enable bootchart2 (and optional bootchart2-done) service:

systemctl enable bootchart2

systemctl enable bootchart2-done

If you are using openSUSE version 13.1 or earlier, go to YaST → (System) → Startup and enter kernel startup parameters:

initcall_debug printk.time = y quiet init = / sbin / bootchartd rdinitrd = / sbin / bootchartd

The next time you start your computer, the /var/log/bootchart.png image will be created to help you further optimize your system startup. For example, if you do not need an AppArmor who cares about security, you can disable the boot.apparmor service through the YaST Service Configuration Module.

Suitable for: openSUSE 11.4, 12.x, 13.1, 13.2, Leap 42.x
