Yes, this is what I'm doing with OSTree. However in the general cross
labeling case it has a subtle issue with PCRE:

There is of course always the potential issue for incompatible future
changes in the file_contexts format.
My current workaround is:

FWIW I don't have an immediate major need for the relabeling API because
we use Anaconda which does initial labeling there. The remaining
use cases for libguestfs apps of debug/repair are still valid, but those aren't
critical path.
