# MiOS system-side installer (FHS overlay path).
#
# This script is invoked by the bootstrap installer on non-bootc Fedora hosts.
# On bootc-managed hosts, do NOT run this -- use `bootc switch` instead.
#
# What it does:
#   1. Refuses to run on bootc-managed hosts (their /usr is read-only composefs).
#   2. Lays down the FHS overlay from this repository's working tree to /.
#   3. Runs systemd-sysusers, systemd-tmpfiles, and reloads systemd units.
#   4. Enables MiOS services.
