Ah he's hard linked symlinks not handled correctly by rpm.

Likely fixable now: at the time you reported, there was a re-release of
a CVE about removing hardlinks on files during erasure which trumped
your bug: the wiser course at the time seemed to be not to to disrupt
the paranoid security types with too much info regarding
	hardlink -> symlink -> setuid/setgid
so that the re-release of the CVE might deploy on schedule.
