# Based on the directions here: https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chroot
# This will take a while to build, with most of the time spent on QT4. There is some redundancy with creating
# multiple clean chroots, but I think this approach is easier and more reliable for most systems.

# Specify a build directory. Defaults to /tmp:
BUILDDIR="/tmp"

# Install devtools if it's not already installed:

Disclaimer: Please follow this guide being aware of the fact that I'm not an expert regarding the things outlined below, however I made my best attempt. A few people in IRC confirmed it worked for them and the results looked acceptable.

Attention: After following all the steps run gdk-pixbuf-query-loaders --update-cache as root, this prevents various gdk-related bugs that have been reported in the last few hours. Symptoms are varied, and for Cinnamon the DE fails to start entirely while for XFCE the icon theme seemingly can't be changed anymore etc.

Check the gist's comments for any further tips and instructions, especially if you are running into problems!

nix-shell and Shebang Lines

A few days ago, version 1.9 of the Nix package manager was released. From the release notes:

nix-shell can now be used as a #!-interpreter. This allows you to write scripts that dynamically fetch their own dependencies.
