Situation: Poking around some system files in
Problem: I managed to accidentally
rm-ed some files, including
/etc/pam.d/system-auth (don't ask...)
Question: What are the ramifications (if any) of removing such files? I dare not log out or reboot for now.
Additional information: Machine is running CentOS 7. Will also be interested to know ramifications on top of just replacing the files.
