- Add reboot.yml playbook with rolling reboot (serial: 1) - Uses systemd reboot.target for NixOS compatibility - Waits for each host to come back before proceeding - Update dynamic inventory to use short hostnames - ansible_host set to FQDN for connections - Allows -l testvm01 instead of -l testvm01.home.2rjus.net - Update static.yml to match short hostname convention Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# Reboot hosts with rolling strategy to avoid taking down redundant services
|
|
#
|
|
# Usage examples:
|
|
# # Reboot a single host
|
|
# ansible-playbook reboot.yml -l testvm01
|
|
#
|
|
# # Reboot all test hosts (one at a time)
|
|
# ansible-playbook reboot.yml -l tier_test
|
|
#
|
|
# # Reboot all DNS servers safely (one at a time)
|
|
# ansible-playbook reboot.yml -l role_dns
|
|
#
|
|
# Safety features:
|
|
# - serial: 1 ensures only one host reboots at a time
|
|
# - Waits for host to come back online before proceeding
|
|
# - Groups hosts by role to avoid rebooting same-role hosts consecutively
