cloud-init is absolute cancer. Its code is horrible. It has no documentation at all.

It took me 5 fucking hours to figure out how to properly configure networking on recent cloud-init (Ubuntu 16.04 cloud image) with local datasource.

It's not mentioned anywhere you need to provide dsmode: local. (but only if you need network-config, besides that everything is fine; someone below noted that -m flag does the same thing, good to know) Of course nobody needs documentation for network-config format either. (cloudinit/net/__init__.py is a protip, enjoy the feces dive)

Oh, and by the way - no, it's not possible to provide network-config to uvt-kvm without patching shit.

Silent Boot in Debian 13

Set this in your /etc/default/grub file:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=3 systemd.show_status=auto rd.udev.log_level=3 vt.global_cursor_default=0"

quiet: Disable most log messages.
splash: Make sure plymouth shows the splash screen.
loglevel: Only show messages with loglevel 3 (KERN_ERR) or lower. Lower levels are more serious.
systemd.show_status=auto: Suppress succesfull messages.
rd.udev.log_level=3: Only show messages with loglevel 3 (KERN_ERR) or lower. Lower levels are more serious.

Are we XLibre yet?

X11 has been, and still is, a vital piece of technology at the core of professional Unix-like workstations since decades. It has a proven track record of supporting enterprise-grade applications with long-term protocol stability and platform compatibility. It has matured over decades. XLibre is an actively developed fork of the X.Org X11 server, initiated by the most active X.Org developer and supported by the open source community.

An incompatible alternative, Wayland, is being aggressively pushed by IBM = Red Hat = Gnome = Fedora = freedesktop.org. However, it is not ready to succeed X11 as it its governance model leads to never-ending discussions and prevents even the most essential functionality from existing. Think twice before abandoning Xorg. Wayland breaks everything!

It is time that the open source community reclaims what was ours to begin with. This page lists distrib
