Hi,

as suggested on this Directory_Replacement page I tried to solve this
problem by adding a little lua scriptlet.
Unfortunately it seems not to work for me so I must be missing some
details here.
You aren't missing anything. The scriptlet doesn't work, as the
transaction is checked by dnf before rpm scriptlets even happen. The
best workaround is to just _not_ change directories to symlinks or
vice versa. How to actually do that depends on the package, though.
Given the recent Change Proposal to hard-link duplicate files, maybe
the simplest option is to just make the symlinks into duplicate
directory copies.

I don't know why that documentation page still exists; I've never been
able to get it to work as documented, and it's been that way for a
long time:
https://pagure.io/packaging-committee/issue/1139
As I understand it, some behaviour of dnf changed a few years ago,
which made the approach documented in the Packaging Guidelines
("Directory_Replacement" page) no longer work.

Hi,

IIRC it still works OK (or to some degree), but can decide not to work in various situations, like "recently" (few months back) for nodejs with specific overlayfs configuration:
https://lists.fedoraproject.org/archives/list/packag...@lists.fedoraproject.org/thread/OKEI2K7GSUHWEF5R5N767LUOJNP7YJQQ/

So there's currently no really good / documented way to handle this case.
(And we should remove the docs for things that no longer work, I agree.)
Sounds good, but then what would be in its place?

I think this is yet another reminder that we should have another kind of workaround for these unfortunate situations. Just removing that without any replacement plan it is not an ideal way forward IMO.

Fabio
Thanks,
Jarek
