Explicit configured file permissions in FileDetails not respected by Deb and Rpm task

[breskeby]

we are configuring file permissions explictly in a copySpec like this:

    modulesFiles = { os, architecture ->
      copySpec {
        eachFile {
          if (it.relativePath.segments[-2] == 'bin' || (os == 'darwin' && it.relativePath.segments[-2] == 'MacOS')) {
            // bin files, wherever they are within modules (eg platform specific) should be executable
            // and MacOS is an alternative to bin on macOS
            it.permissions.unix(0755)
          } else {
            it.permissions.unix(0644)
          }
        }
...
...

this stopped working in 12.1.0 due to the workaround I have found here:

gradle-ospackage-plugin/src/main/groovy/com/netflix/gradle/plugins/utils/FilePermissionUtil.groovy

Lines 32 to 58 in cd8bccb

	static int getUnixPermission(FileCopyDetails details) {
	int newApiMode = details.permissions.toUnixNumeric()
	// Gradle 9.0 permissions API may not detect executable bits correctly
	// Fallback: check the actual file permissions if the API seems wrong
	try {
	if (details.file?.canExecute() && (newApiMode & 0111) == 0) {
	// File is executable but new API didn't detect it - use filesystem check
	boolean readable = details.file.canRead()
	boolean writable = details.file.canWrite()
	boolean executable = details.file.canExecute()
	if (readable && writable && executable) {
	return 0755 // rwxr-xr-x
	} else if (readable && executable) {
	return 0555 // r-xr-xr-x
	} else {
	return 0644 // rw-r--r--
	}
	}
	} catch (Exception e) {
	return newApiMode
	}
	return newApiMode
	}

I think we can workaround this in this particular szenario by fixing the initial permissions but I would like to have the ultimate control over the permissiosn set in our packages in the task itself. I don't understand yet what the original issue with the permission api is that caused this but happy to drive this forward. at least having a way to step out of that workaround would be great for us as we explicitly configure the permissions for our system packages all over the place.
