# Add an extra user, set password, add to sudoers
#   Apparently, "ubuntu" user is not yet created, by the time late_commands runs

# Addendum: handling password hashes, based on:
# http://unix.stackexchange.com/questions/52108/how-to-create-sha512-password-hashes-on-command-line
# 
# Get hash for password "paperino":
#  python -c "import crypt, getpass, pwd; print crypt.crypt('paperino')"
# Check a given hash to verify it corresponds to some password:
# - select the hash portion up to the end of the 'salt', namely the
#   piece of string comprised between $6$ and the next '$' character
# For example:
#  python -c "import crypt, getpass, pwd; print crypt.crypt('paperino', '\$6\$Ck.Gim7WqVzsv8j9\$')"
