Hi, I had set the noexec mount option on /tmp while installing Debian 9 using firmware-9.5.0-amd64-DVD-1.iso.
But after the installation was completed, the mount option was found missing. This same behaviour is noticed when installing the OS using preseed. root@mountoptions:~# mount | grep /tmp /dev/sda5 on /tmp type ext4 (rw,nosuid,nodev,relatime,data=ordered) Thanks, Augustus.
