CI is broken and the issue seems to be not a buildkit change but a change in busybox image used in test.

 # docker run -it --rm busybox:1.31 cat /etc/group | grep no
nogroup:x:65534:
 # docker run -it --rm busybox:1.32 cat /etc/group | grep no
nobody:x:65534:

We should probably also pin to a specific version to avoid this. But corrected the tests atm.

@tianon I assume this change was intentional and we don't expect a rollback.
