Current evaluation

PR #473 merged as commits 0089540 (main) and 163f560 (hotfix/1.19): added a mount_cache flag to BaseProvider.setup() and pass mount_cache=False when configuring LXD base instances, so cache mounts can't break copying.

Resolution: closed resolved

Reason: The PR itself was merged after review by two maintainers; the change is present in craft_providers/base.py (setup(mount_cache: bool = True)) and craft_providers/lxd/launcher.py which calls base_configuration.setup(executor=base_instance, mount_cache=False) with the comment that base instances must not mount cache dirs since deleting them would break instance copying.
