RHCSA 9.1: Local user accounts

Creating a service account, moving a home directory, and deleting users with and without their files.

Before you start

The lab checks that there's no user svcbak or carol and that UID 2001 is free. Task 3 deletes the users the first two tasks create, so the lab runs a small service, le-lab-watch, that notes their /etc/passwd lines (and what's in /home/carol2) every second for the check. Do the tasks in order, and look at the results of each before you go on.

Tasks

1. Create a user svcbak with UID 2001, the comment Backup account, and no login shell.
2. Create a user carol, then move her home directory to /home/carol2 with its files, and change her comment to Carol Smith.
3. Delete carol together with her home directory, and svcbak without it. Then find the files left behind in /home that belong to nobody, and write their paths, one per line, to /root/lab-answers/3.

Hints

• useradd -u -c -s /sbin/nologin; getent passwd svcbak.
• useradd, usermod -m -d, usermod -c; ls -a /home/carol2.
• userdel -r, userdel; find /home -nouser.
