alpine linux firefox box setup script

firefox-setup.sh

# This rest of this script assumes that you have recently installed alpine linux, and that you have already 
# set up your own user account, and logged into it. Here's how you set up a user account if you would like to
# do that before continuing, (assumes you are logged in as root, and that you want to call your account "myuser").
# Parts of this section and the below ones are based on https://wiki.alpinelinux.org/wiki/Dwm 
#    adduser myuser
#    apk add sudo nano
# You need to edit the /etc/sudoers file, to add a line for your user below the one for the root user in the
# "User priviledge specifications section". That is the lines should look someithing like: 
# ##.
# ## User priviledge specifications
# ##
# root ALL=(ALL) ALL
# myuser ALL=(ALL) ALL
# 
# It is recommened that you use `visudo` to edit the sudoers file, since that prevents saving
# if there are syntax errors etc. Nano should work too though.
# 
# You can switch to your new user account with
#     su myuser
# You'll probably want to follow that up with
#     cd ~
# to get to your home directory.

# As of now, it seems like `wpa supplicant` just isn't setup to start automatically after an install.
# See https://gitlab.alpinelinux.org/alpine/aports/issues/8025
# So here's what you can do to set it up to automatically start:
# start up for now
#    sudo rc-service wpa_supplicant start
# check with ping if you like
#    ping -c 5 alpinelinux.org
# download this script (long url version)
#    wget https://gist.githubusercontent.com/Ryan1729/4dabf86ad7f37f95c1613d4551b71779/raw/7f755ee7b1a330995369dde60bfbf53161e84864/firefox-setup.sh
# download this script (short url version)
#    wget https://git.io/JvgNU
# then you can run it to get the rest set up.

die () {
    echo $1; exit 1
}

test ! -e temp || die 'Temp file already exists. Move it so it does not get overwritten.'
