The real problem here is in the assumed goal of "create a non-relocatable subpackage".
Every path in every package can be relocated by --relocate /old/path=/newpath. The
only restriction is that only full directory/file paths, not partial paths, can be relocated.
E.g. given a path like /A/B/C/abc, one cannot relocate with a file prefix (or pattern) like
The only current usage for a Prefix: (and multiple Prefix:'s or Prefixes: are permitted) is
to automatically disable a warning/error message that can be overridden by another option.
If you want to use Prefix:, then specify all relocations in all subpackages. The behavior
for a "non-relocateable" subpackage will always depend on what options were used
to install that package, and there is no way (nor should there be: only the end-user,
not the builder, can determine what paths are useful/needed in general) to prevent
--relocate from being used with appropriate overrides.
Note that the modestly serious design flaw with relocateable paths in *.rpm packages is that
the relocations are not remembered persistently. So if you decide to relocate some
path, then you also need to add --relocate on every future install.
The other flaw is that relocations are per-transaction (or CLI invocation), not per-package.
This means that if you have two packages with an identical path which you want to
relocate in one package but not the other, then the 2 package installations MUST be
in in different transactions and installed separately.
