Last updated on SEPTEMBER 23, 2022

Linux OS - Version Oracle Linux 7.7 with Unbreakable Enterprise Kernel [4.14.35] and laterLinux x86-64

/tmp is not automatically mounted after reboot even though an entry is present in /etc/fstab
Below outputs show an example of the issue:
# uptime 16:44:11 up 2 min, 1 user, load average: 0.21, 0.55, 0.44
# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 252G 0 252G 0% /dev tmpfs 252G 817M 251G 1% /dev/shm tmpfs 252G 11M 252G 1% /run tmpfs 252G 0 252G 0% /sys/fs/cgroup /dev/mapper/VolGroupXXX-LogVolRoot 30G 25G 3.2G 89% / /dev/mapper/VolGroupXXX-LogVolVar 7.8G 588M 6.8G 8% /var /dev/sda1 477M 234M 218M 52% /boot /dev/mapper/VolGroupSys-LogVolHome 2.0G 12M 1.8G 1% /home tmpfs 51G 0 51G 0% /run/user/0
# cat /etc/fstab /dev/mapper/VolGroupXXX-LogVolRoot / ext3 defaults 1 1 UUID=xxxx6a54-xxxx-xxxx-xxxx-121xxxxxxx83 /boot ext3 defaults 1 2 /dev/mapper/VolGroupXXX-LogVolSwap swap swap defaults 0 0 /dev/mapper/VolGroupXXX-LogVolTmp /tmp ext3 defaults 1 2 /dev/mapper/VolGroupXXX-LogVolHome /home ext3 defaults 1 2 /dev/mapper/VolGroupXXX-LogVolVar /var ext3 defaults 1 2
Running "mount -a" mounts /tmp without any issues.
