Unit number is increasing in latest juju version.

[Sunitha Radharapu]

Hi Matt,

I am a little bit confused here, bug description says it should be as
unique id. If it is a bug and you are going to fix in future juju releases
then we no need to change our amulet tests.

If it is a new feature then we will change our upcoming charms accordingly,

Thanks,
Sunitha.

Hi Mark, Sunitha,

My apologies, I should have included the explanation in the original email.

This was a change to address a long standing bug:
https://bugs.launchpad.net/juju-core/+bug/1174610

There's a discussion in the bug report, but the summary is that in most
cases it's desirable to have the unit id be unique across the life of an
environment. Otherwise you loose the identity of a unit across relations.

We were already numbering the machines in the same way, so this change also
gives us consistency between machine and unit numbering systems.

Thanks

Matty

  Thanks Sunitha. Matty, deeper question is - was this an intended change
  in behaviour, and what's the rationale?
