rHG705c37f22859: upgrade: add support for experimental safe share mode
Summary

Recently we introduce the share-safe functionality which makes shares share
requirements and config of share source. This patch adds support to
debugupgraderepo command to upgrade repository to share-safe mode when
format.exp-share-safe config is enabled.

Upgrades the shared source and current shared repository '

Can we upgrade share ? I though it wasn't possible ? And it is probably safer to deny any upgrade from a share.

to use safe method of sharing which will make requirements '
and configs being shared.'

Maybe clarify this using. It makes shares inherit repository requirement and configuration from its source.

What do you think ?

1463–1465

Could have have old share automatically pick up the source requirements and move to share safe mode ? That would seems safer.

We need to test that downgrading is working too.

They will be required to re-shared. Also I am not sure if we have a way to list all the shares of the current repository.
