In response to this thread: * dropping and interpolating are both fraught with problems
Therefor: * please implement a queue * please ensure that there is an externally imposed timeout on every action (so the queue never gets fully blocked even if one gets stuck) * think carefully about how to handle a failure - does that invalidate the node, or do we initiate an attempt to reset the BMC and re-establish control * provide feedback on the queue on commands, e.g. $ maas power-off node1 Queue of power actions on node1: * reboot (for admin) in progress * reboot (for admin) * pxe-boot (for fred) then will power-off for you. $ maas power-off node2 Powering off node2 for you now. While that may seem pedantic, it's most understandable to the user because they don't have to know what MAAS is doing or why; MAAS is just doing what it has been told, and they can talk to the user in question if it's been told something silly.
