util-linux will merge lastlog2, I have no idea about wtmpdb, this wasn't a topic yet before my vacation. procps-ng kills reading files directly and will use systemd, patch got accepted but not yet merged. The current patches for util-linux do the same. I haven't looked at the latest PR for shadow, but they planned the same. So nobody seems to care about "backward compatibily" with a time where tools like "last" did not yet exist. > Also, the question about /var/adm/btmp remains. Is there a use-case, for which it is __reliable__ useable? Until now, nobody could tell me one and nobody cared.
