non-HA has reset :)
jokes aside, we evaluated the option of the clean shutdown for HA
and changing it for the stop command. But it was seen is minor (annoying)
problem and other more important stuff let me forgot about that.

We can pick it up again, if someone is willing to open a bug report at
https://bugzilla.proxmox.com/ to help me track this issue would be great.
I can do it too myself tomorrow..
As changing the behaviour between releases seems not that good, we have
a) postpone it to 5.0
b) find another way for now.

CCed Kevin Lemonnier so that he know I saw his answer too :)
