# TinyInstaller Bootstrap
#
# This script downloads and launches the TinyInstaller deployment binary as part
# of a user-initiated operating system deployment workflow.
#
# TinyInstaller is a proprietary operating system deployment automation service
# for supported VPS and server environments owned or controlled by the user.
#
# The downloaded binary may perform operations such as:
#   - disk partitioning
#   - formatting storage devices
#   - deploying operating system images
#   - installing bootloaders
#   - rebooting the system
#
# These operations are the intended functionality of TinyInstaller and require
# root or equivalent administrator privileges. Running this script may erase all
# data on the target server.
#
# Use only an installation command generated by TinyInstaller.
