# Configure biscayne OS-level services for agave validator
|
||
|
|
#
|
||
|
|
# Installs a systemd unit that formats and mounts the ramdisk on boot.
|
||
|
|
# /dev/ram0 loses its filesystem on reboot, so mkfs.xfs must run before
|
||
|
|
# the fstab mount. This unit runs before docker, ensuring the kind node's
|
||
|
|
# bind mounts always see the ramdisk.
|
||
|
|
#
|
||
|
|
# This playbook is idempotent — safe to run multiple times.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# ansible-playbook -i biscayne.vaasl.io, playbooks/biscayne-boot.yml
