Having a SSD - it is recommended to mount /tmp as tmpfs.Examples:https://askubuntu.com/questions/550589/best-way-to-mount-tmp-in-fstabhttps://yktoo.com/en/blog/post/233https://askubuntu.com/questions/173094/how-can-i-use-ram-storage-for-the-tmp-directory-and-how-to-set-a-maximum-amountThe mounting options are different in each example - why???The default Ubuntu 16 installation sets the mounting options for root (/) as (from /etc/mtab):/dev/sda1 / ext4 rw,relatime,errors=remount-ro,data=ordered 0 0Ergo all other options - as suggested in the examples/links - shouldn't be applied.Some of the mounting options in the various examples on the web are:defaults,noatime,mode=1777or:defaults,noatime,nosuid,nodev,noexec,mode=1777,size=512MBut:Having noatime feels useless because that the data is stored in RAM which is fast anyway.Why nosuid,nodev,noexec ?How do they know whether softwares are dependent on certain options or not?I think it is best to stick with the default permissions that the installation applied, meaning:rw,relatime,mode=1777,uid=0,gid=0In order to ensure proper operation of various softwares:  The permissions are 1777 because that the default permissions for /tmp are also drwxrwxrwt (see stat -c %a %n /tmp).The uid and gid are root because that /tmp has the same.Is there something which I'm missing here?
