I mount /tmp with nodev, nosuid, and noexec options to increase the security of my Linux based web server. And, whenever I ran apt-get install or apt-get upgrade command, I am getting the following error:

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.2.0-43-generic
Found initrd image: /boot/initrd.img-3.2.0-43-generic
....
ldconfig deferred processing now taking place
Processing triggers for initramfs-tools ...
update-initramfs: Generating /boot/initrd.img-3.2.0-43-generic

How do I fix this problem without compromising security of the data or web-server?
