Troubleshooting the etc Directory
The cl-support script replicates the /etc directory, however, it excludes certain files, such as /etc/nologin, which prevents unprivileged users from logging into the system.
The following shows example output from ls -l on the /etc directory structure, which cl-support creates.
cumulus@leaf02:mgmt:~$ ls -l /etc
