You need to report what you actually did, not what you think you achieved. > But after the installation was completed, the mount option was found > missing. This same behaviour is noticed when installing the OS using > preseed. We can only guess. The most likely is that during installation you edited /etc/fstab. Unfortunately, that's the fstab for the system that's running *during installation*. The system you are building is in /target, so you would need to edit /target/etc/fstab. However, I'm not guaranteeing when /target/etc/fstab is last modified by the installer. (For example, modifying /target/etc/network/interfaces can be futile as the installer modifies it at the very last step.) > root@mountoptions:~# mount | grep /tmp > /dev/sda5 on /tmp type ext4 (rw,nosuid,nodev,relatime,data=ordered) Cheers, David.
