# This script installs the tinycore linux from a the Core Bootable ISO. It is
# a very tipical installation, using the whole disk as ext4 primary partition.
#

#
# 2) Create a virtual machine and boot the ISO. (press [Return] when asked)
#
# 3) Download and run this script:
#
#         tce-load -w -i openssl.tcz                  <- enable ssl (for https)
#         wget git.io/tinycore-install                <- download script
#         sh tinycore-install                         <- run
#
# 3) What tinycore-install does:
#    - Create and format a single partition using whole disk space
#    - Install Kernel
#    - Install GRUB
#    - Setup GRUB to boot from disk
