# - Arguments
# rootfs_dir=$1
#
# - Optional environment variables
#
# EXTRA_PKGS: Variable to add extra PKGS provided by the user
#
# BIN_AGENT: Name of the Kata-Agent binary
#
# REPO_URL: URL to distribution repository ( should be configured in 
#           config.sh file)
#
# Any other configuration variable for a specific distro must be added 
# and documented on its own config.sh
# 
# - Expected result
#
# rootfs_dir populated with rootfs pkgs
# It must provide a binary in /sbin/init
#
# Note: For some distros, the build_rootfs() function provided in scripts/lib.sh
#       will suffice. If a new distro is introduced with a special requirement,
#       then, a rootfs_builder/<distro>/rootfs_lib.sh file should be created
#       using this template.
