Update Config Tree
When you update Legato using the Software Update API, this is what happens with config trees:
- the updated new system automatically inherits (copies) the config trees from the old system.
- if a roll-back happens, the updated system config trees (possibly corrupted) are deleted, and the old system is restored (along with the old config trees in the same state as before the update).
- Note
- Trees that are no longer accessed by an app are currently saved until you use the Config Tree Admin API “config” tool or
rm”
to delete them.
