Setting a node temporarily to offline or online is not persisted to disk. Normally this is not an issue but each time I have to restart Jenkins this a big issue. Nodes that should be offiline after a restart is not and nodes that should be online is offiline. The only way to update the temporarily offline status is to change something in the node configuration and save.

I believed this worked in the past I do not know the version. I do not restart often and it took me some time to notice this.
