Jolla doesn't use dhclient; it uses connman's builtin gdhcp client.
EDIT: Again, during "security crazes" please remember to keep your brain turned on. There's a shitton of people (e.g. stackoverflow) who is right now posting "instructions to solve the bash bug" which include absurd things such as replacing your distro's bash with some random online version. Without proper care, that's even more stupid than plainly doing nothing.
This doesn't necessarily apply to nieldk's packages, which I think one can trust (hehe ;P), but please remember to be generally cautious about this.
