Install /etc/sudoers.d/puavo-bootserver from the package,
it is okay.
Clean things up a bit.
I do not think that dhcpd-user needs to belong to puavo-group...
it did not work anyway, and we use sudo for the same effect.
Setup /etc/pam.d/common-password elsewhere, does not belong here.
Remove root password setup from puavo-bootserver-install.
Move networking setup elsewhere, provide instructions for setting
it up.
