A Brief Tour of the Makepkg Process: What Makes a Pacman Package

Introduction

This is a terse document covering the anatomy of a package built for the pacman package manager.

The following example commands can mostly run verbatim to manually create a

Commit Message Format

This specification is inspired by and supersedes the [AngularJS commit message format][commit-message-format].

We have very precise rules over how our Git commit messages must be formatted. This format leads to easier to read commit history.

Each commit message consists of a header, a body, and a footer.

To remove a submodule you need to:

Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule

How to mount a qcow2 disk image

This is a quick guide to mounting a qcow2 disk images on your host server. This is useful to reset passwords, edit files, or recover something without the virtual machine running.

Step 1 - Enable NBD on the Host

modprobe nbd max_part=8

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
