At some point in time I had a couple machines that had cronjobs running as a non-root username that would ensure a mounted directory exists and was working. I don’t remember why I didn’t use root at the time. Since mount and umount require sudo access, the cronjob would always fail.
This will allow a specific username access to mount and umount without the need to use sudo.
First open the file using visudo (you must use visudo).
sudo visudo -f /etc/sudoers.d/myOverrides
Then add the following line, replacing MYUSERNAME with your system username.
MYUSERNAME ALL=(ALL) NOPASSWD:/bin/mount, NOPASSWD:/bin/umount
