Delete

Delete a sysctl parameter by removing its drop-in file from /etc/sysctl.d/. The parameter value is not reset in the running kernel — it persists until the next reboot or until you set a new value:

$ osapi client node sysctl delete --target web-01 \
    --key net.ipv4.ip_forward

  Job ID: 550e8400-e29b-41d4-a716-446655440000

  KEY                   CHANGED
  net.ipv4.ip_forward   true

If the parameter does not exist, changed: false is returned:

$ osapi client node sysctl delete --target web-01 \
    --key net.ipv4.ip_forward

  Job ID: 550e8400-e29b-41d4-a716-446655440000

  KEY                   CHANGED
  net.ipv4.ip_forward   false

Broadcast to all hosts:

$ osapi client node sysctl delete --target _all \
    --key vm.swappiness

  Job ID: 550e8400-e29b-41d4-a716-446655440000

  HOSTNAME  KEY           CHANGED
  web-01    vm.swappiness  true
  web-02    vm.swappiness  true
