||File /usr/share/man/man1/extlinux.1.xz conflicts with the package syslinux-4.04-alt16.x86_64. Moreover, the packages have no explicit conflicts with each other. You should add explicit conflicts, or, if conflicts are avoidable, consider using alternatives.
||The package consists of architecture-independent data in /usr/share, while it is an architecture-dependent package. This is wasteful of mirror space and bandwidth, as we then end up with multiple copies of this data, one for each architecture. If the data in /usr/share is not architecture-independent, it is a policy violation, and in this case, you should move that data elsewhere.
