I know this package can update minor version, say 12. 04. 02 to 12. 04. 04 and even bigger jobs. But does it also do Major version jumps - say version 12 to 13 or 14? Without any human interaction.
Thinking about making a private mirror and when I put version 14 (tahr) in the mirror the unattended-upgrades package should update all the slaves to 14 automagically.
