But cowsay doesn't depend on pcre2, libpcre2 got installed before 
dependencies
installation but during distupgrade stage. So DEPENDS is not an option
(or how can we depend on every package?).
Probably ISAR_REBUILD_ESSENTIAL_PKGS with your fix will resolve it.

Speaking about ISAR_REBUILD_ESSENTIAL_PKGS, we should add a testcase (or 
better
even a real usage in meta-isar/meta-test) for this feature.
