SSH uses /etc/ssh/moduli file for DH exchange key alogithm. Only root has write permissions to modify the /etc/ssh/moduli file.
Assume that we modify the /etc/ssh/moduli file for some reason (Ex - removing prime numbers less than 2048 bits or add new prime numbers to moduli file).
What happens when I upgrade my Ubuntu to a new version (14.04 to 16.04)?
Does the moduli file gets overwritten (or) changed?
