Code review comment for ~danilogondolfo/network-manager/+git/ubuntu-1:preinst_script_fix

I think this makes sense. Even if --purge removes it, I think it's fine as it's a conscious decision to purge the package and all of its configuration. I think the NM configuration would be wiped out when --purge is used without the netplan integration anyway, right?

For sure seems a better placement for this than /root.
