What this card says
Why do we need it?
A manual mount is lost after reboot unless you persist it.
What is it?
Amazon Linux EFS mount helper uses amazon-efs-utils. fstab keeps the mount across reboots.
How to do it
yum/dnf install amazon-efs-utils → mkdir /mnt/efs → mount -t efs -o tls fs-id:/ /mnt/efs → add fstab line with _netdev.
_netdev
Example
After reboot, df -h still shows /mnt/efs and the shared hello.txt.
