Description of problem:

The file /var/log/btmp is not rotated and can grow to enormous sizes. The closely related file /var/log/wtmp is mentioned in /etc/logrotate.conf and will be rotated, /var/log/btmp should be treated the same way.


Version-Release number of selected component (if applicable): 3.7.4-9


How reproducible: always


Steps to Reproduce:
1. setup system with packages initscripts and logrotate installed 
2. let /var/log/btmp grow (you can generate failed logins that will be logged in this file with a script for fast reproduction)
  

Actual results: /var/log/btmp will not get rotated and can grow to enormous size


Expected results: /var/log/btmp should be rotated with logrotate after it grows to a certain size, just like /var/log/wtmp


Additional info:

This is a possible regression on bug #117844.

The Specfile mentions /var/log/btmp only once on line 188:

"- Add section to logrotate.conf for "/var/log/btmp" (#117844)"

However, no such section is added to logrotate.conf. According to the specfile logrotate.conf is copied from the source tarball and installed into the system without further changes:

line 52: install -m 644 examples/logrotate-default $RPM_BUILD_ROOT/etc/logrotate.conf
line 65: %attr(0644, root, root) %config(noreplace) /etc/logrotate.conf

This bug might also affect RHEL 4 and 6, I haven't checked.

Also, I'm wondering about the comment "no packages own wtmp -- we'll rotate them here" in logrotate.conf. According to RPM, /var/log/wtmp and /var/log/btmp are owned by the initscripts package, so maybe it would be a good idea to move rotation of /var/log/wtmp from logrotate.conf into an extra file in /etc/logrotate.d/initscripts and put that file into the initscripts package or something like that.
