   Anything which you had permission to do when using bst 1, like setting `xattrs` (which will require root) should work equally with bst 2 *when executed in the same environment with the same privilidges*.
   
   Maybe this usually works in CI under root user with bst1, but was tried as a regular user on a local workstation ?
   
   Did this happen as a result of https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/blob/abderrahim/bst2/elements/vm/minimal-ostree/image.bst#L35 ? or somewhere else ?
   
   One thing I noticed is that this branch uses `ostree` from `bst-plugins-experimental` instead of from `buildstream-plugins`, which should be okay, but it also appears to use the `ostree_mirror` plugin, which simply does not exist anywhere:
   
   ```
     - origin: junction
       junction: plugins/bst-plugins-experimental.bst
       elements:
       - check_forbidden
       - collect_initial_scripts
       - collect_integration
       - collect_manifest
       - flatpak_image
       - flatpak_repo
       - makemaker
       - modulebuild
       - snap_image
       sources:
       - cpan
       - git_tag
       - git_module
       - ostree
       - ostree_mirror
       - patch_queue
       - pypi
       - zip
   ```
   I checked the ref at `plugins/bst-plugins-experimental.bst` which appears to be at the tip of master, but there is no such plugin.
   
   Given that this non-existent plugin is used by the very same element: https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/blob/abderrahim/bst2/elements/vm/minimal-ostree/image.bst#L102 it is hard to conceive of how the build got far enough to produce this error.
   
   Can I get more information on how to reproduce this ?
