Open firewall for DNS on both TCP and UDP

nsupdate uses UDP by default unless the request is too large.  Open DNS to both
TCP and UDP rather than just TCP.
Use mount point rather than directory for quota

Use mountpoint for quota rather than directory in filesystem.  "quota -f"
expects a mount point or device so grab that from "df".  Series of shell
commands taken from oo-init-quota.
