Hi, I believe your bug got too late as the new samba has hit testing today, for what I saw FAM may not be a wanted feature, it is not listed on the build dependencies and in fact arches other than i386, like amd64 for example, don't seem to have a dependency on FAM.
If FAM was really not intended I think we should disable it on our config and upload with high urgency to get a version without FAM to testing ASAP. Regards... -- Santiago García Mantiñán
