Did something change in cpio, or has it always been broken for regular file
to directory replacement too, and our docs were thus always incomplete ?
It was always this way.
The same for replacing a file with symlink. Or vice versa.
Ok, so the packaging docs should say that /any/ change in file type between
dir, regular & symlink needs special handling with lua scriptlets. I'll see
about submitting a docs patch.
This topic has come up a few times this year, and it seems like working
around RPM's limitations with Lua scripts doesn't work in some
situations, including system upgrades:
https://bugzilla.redhat.com/show_bug.cgi?id=2406164
I'm seeing a fair number of users report that this issue prevents them
from updating to Fedora 43, and many of them are waiting, expecting the
packager to resolve the problem.
I would suggest that Fedora's policies should express a very strong
preference for avoiding Lua scripts by simply renaming the directory
that contains contents that need to change.
That is, if "/usr/lib64/<app>/foo" is going to change from a directory
to something else (or visa versa), then the package should simply use a
different prefix, such as "/usr/lib64/<app>2"
I think this approach is similar to using "epoch" to resolve a version
ordering issue.
Such a change could be reverted after two Fedora releases.
