Public bug reported:
[ Impact ]
* The following line has been found in users logs when trying to log in to
their systems:
login[2449]: PAM unable to dlopen(pam_lastlog.so):
/usr/lib/security/pam_lastlog.so: cannot open shared object file: No such file
or directory
This results in users reporting that they cannot login to their systems.
They can perhaps do so with other login methods (ssh, login, gdm, xdm, etc)
that don't depend on the lastlog binary, but that doesn't suffice.
* The upload fixes the issue by dropping pam_lastlog.so from all
config, as well as not installing the lastlog binary.
[ Test Plan ]
* Install Trixie in a VM and try to log in post installation. Whether
or not login fails, check the journal for the aforementioned message, or
if you login via ssh, the last login message shouldn't appear.
[ Where problems could occur ]
* If there were login methods entirely dependent on pam_lastlog.so, I
imagine users using these login methods would have trouble. Though this
pam config I don't believe is widely used.
