It's not just about readers. It's also about writers.
/var/log/btmp:
Log of all attempted bad logins to the system. Accessed via the lastb
command.
"Empirical" testing shows that login writes to btmp. I infer, from that
description given at TLDP, that everything that logs a bad-login attempt (e.g.,
login) ought to be writing to this file. It is NOT an SSH-specific thing.
I assumed that since LFS was creating it in the first place, that LFS was the
right place to keep it. Unfortunately, the default LFS perms break downstream
assumptions about /var/log/btmp, and that's what's being fixed.
