Description Michal Sekletar 2023-03-21 12:21:35 UTC
Description of problem:
Users are advised to reload systemd whenever the /etc/fstab is edited so that systemd mount units that correspond to lines in /etc/fstab are regenerated by the systemd-fstab-generator. mount utility should remind users to do that in case they forgot.

Version-Release number of selected component (if applicable):
util-linux-2.32.1-41.el8

How reproducible:
deterministic

Steps to Reproduce:
1. mkdir -p /tmp/testmnt
2. echo 'tmpfs /tmp/testmnt tmpfs defaults 0 0' >> /etc/fstab
3. mount -a -t tmpfs

Actual results:
tmpfs is mounted in /tmp/testmnt, but no hint is printed.

Expected results:
tmpfs is mounted in /tmp/testmnt, but following hint is printed.

mount: (hint) your fstab has been modified, but systemd still uses                                                                                                    
       the old version; use 'systemctl daemon-reload' to reload.
