+dropbear will generate host keys on first connection. It's (probably) good that the
+key is generated on-device and also that we wait until there's some randomness.
+It's not so good that it will only write the key to DSS_PRIV_FILENAME which is
+hardcoded to /run

+What do we need for ipv6?
+
+-  upgrade ppp to something with an ipv6-up-script option, move ppp and pppoe derivations into their own files
+-  get ipv6 address from pppoe
+-  get ipv6 delegation from DHCPv6
+-  support dhcp6 in dnsmasq, and advertise prefix on lan
+-  firewall settings

+Making hydra build the docs is straightforward, but making it

+Should hydra push the docs to www.liminix.org or should www.liminix.org

+We have an odhcpc script that preserves the prefix delegation from the
+ISP.  We need a service that notices whenever the state is
+available/has changed, and updates the LAN IPv6 address.
+
+The service can depend on odhcp
+
+add inotify to packages
+use writeFennelScript with that dep
+see if it works
