| Surely, it's not related to Trinity.
i kind of figured as much, but in that some (well, one that i know of) of the configuration modules (user administration) in the trinity system settings suite has not worked for ages, it could be that there was some little flakiness there.

i'm running that version, until 14.04LTS plus the appropriate trinity for it come out, wired all the time on this machine.

apparently, it is kosher to replace the linked resolv.conf with a real file, but the better method is to add a dns-nameservers line to /etc/network/interfaces. so i've done that and we'll see how it fares!
thanks very much.
