# Do an update to make sure all is, well, updated!
pacman -Syu

# Install base-devel which includes gcc and jazz.
pacman -S base-devel

# Create temp dirs for installing stuff
mkdir ~/tmp
cd ~/tmp

# Install Yaourt. Why yaourt instead of pacaur? Because pacaur doesn't allow
# itself to be ran as root, even though all we have is root in the container,
# and I don't want to bother fiddling with users just for this. Yaourt on the
# other hand works fine for this.
# ----------- package query for yaourt -----------
git clone https://aur.archlinux.org/package-query.git
cd package-query
makepkg -si
cd ..

# ----------- yaourt itself -----------
git clone https://aur.archlinux.org/yaourt.git
cd yaourt
makepkg -si
cd ..

# Install htop and cowsay cause they are awesome
yaourt -S htop cowsay

# And say what the IP address is to the terminal.
