I can agree with you on this.

I added the following two lines to my rkhunter configuration file: $ grep keyutils /etc/rkhunter.conf RTKT_FILE_WHITELIST=/lib/x86_64-linux-gnu/libkeyutils.so.1.9 USER_FILEPROP_FILES_DIRS=/lib/x86_64-linux-gnu/libkeyutils.so.1.9 and this seems to work around the issue. Thanks a lot for your research effort, it is much appreciated! This bug report may probably be closed. In the meanwhile, I reported the corresponding [bug #951366] against rkhunter: let's see what the Debian Security Tools maintainers think... [bug #951366]: <https://bugs.debian.org/951366> -- http://www.inventati.org/frx/ There's not a second to spare! To the laboratory! .....................................................
