In general I would not expect that to work.  RHEL to CentOS is a special
case because they're really the same platform --- if it didn't work, you'd
have grounds to file a bug against the CentOS maintainers.  But, say, RHEL
to Debian likely wouldn't work, and neither set of maintainers would
consider an ABI-compatibility complaint to be a valid bug.

Doesn't matter if the core system itself doesn't work, which it wouldn't
in cross-platform cases.
