Configure /var/tmp/fstab Permission.
Copy the file /etc/fstab to /var/tmp/fstab. Configure var/tmp/fstab permissions as the following:
Owner of the file /var/tmp/fstab is Root, belongs to group root
File /var/tmp/fstab cannot be executed by any user
User natasha can read and write /var/tmp/fstab
User harry cannot read and write /var/tmp/fstab
All other users (present and future) can read var/tmp/fstab.
Solution:
cp /etc/fstab /var/tmp/
/var/tmp/fstab view the owner setfacl -m u:natasha:rw- /var/tmp/fstab setfacl -m u:haryy:---
/var/tmp/fstab
Use getfacl /var/tmp/fstab to view permissions
