Font Configuration in Linux

A computer font (or font) is an electronic data file containing a set of glyphs, characters, or symbols such as dingbats.

Most computer fonts used today are in either bitmap(BDF) or outline data(otf/ttf) formats.

Many non-English users have problems with their language's rendering, at least Persian users have problems with viewing Persian charactars that can happen because:

Proper fonts are not installed/found by fontconfig. Click here
Fontconfig order is wrong and the latin fonts are above Persian fonts and don't have a good support that causes problems. Click Here

Longhorn best practices

The following settings are provided as an example how longhorn should be configured in a production cluster, especially if it is deployed on Hetzner Cloud infrastructure.

Hetzner server nodes provide local storage and allow up to five attached volumes (with a size of up to 10TiB each) Local storage is provided by NVMe storage and therefore is much faster than the attached volumes, but limited in size (max 300GiB usable).

It is assumed that the cluster creation is already done, e.g. via terraform scripts provided by the great kube-hetzner project.

	This customization method references "https://lunar.computer/posts/persistent-customizations-proxmox-60/" and has been fixed and tl;dr by @edisonlee55.

	Note: If you are logged in as "root", leave out "sudo" in the commands below.

	1. Create folder "/usr/share/custom/" and "/usr/share/custom/backup"
	$ sudo mkdir /usr/share/custom
	$ sudo mkdir /usr/share/custom/backup

	2. Backup "proxmoxlib.js"
	$ sudo cp /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js /usr/share/custom/backup/
