Yes! My patch is a crude edit of Chris's patch to neutralise this
removal but it is valid and works.

I think in retrospect that it might be clearer to have another quilt
patch layered on top of his patch.

Lastlog was already written by pam_lastlog.so before trixie and the
replacement is pam_lastlog2. The tooling to read btmp was removed by
util-linux.

So I'm not sure there would be any benefit from reversing the rest of
the patch to be worth the increased delta from Debian. Bear in mind that
the patch wasn't just about dropping utmp, it was also about taking over
login from another source package.

An alternative approach I considered was to include code to read the
systemd-style login records directly in 'w' but that seemed like too
much for a patch and it would certainly take more time!
