comment root full Linux. No free blocks
This allowed me to find the culprit on my system - nothing to do with mount-shielded volumes. I had a backup process left hanging that had consumed 90% of root volume in temp files. lsof +L1 listed them all very simply.

Sure, but you set it in listen directives, and the options are applied per host:port pair.

comment Which binlog format to use for MySQL Replication?
I don't know for sure - it's really an internals question, but there are examples of it happening, and documentation on how it's decided.

comment Spoofing NS records for pre-transfer DNS testing
I'm already placing a local DNS in front of the normal one and having it return static records instead of looking them up (which is a very limited kind of split DNS I guess). As far as I can see, this works (in that when I do a manual NS lookup on the domain (which involves querying the old DNS host), my local DNS is returning the spoofed IP), but for some reason that's not enough to make it get everything else from there.I have a suspicion that this is more about how the OS does lookups in general than the workings of DNS.

comment Spoofing NS records for pre-transfer DNS testing
I know I can look up NS entries individually, but what I want is to spoof the whole machine to look at the new DNS, as if I could provide the @newserver option to browsers, email clients etc. What I was trying to do is make a local DNS server override the IPs for the old host's name servers to point at the new one, so a lookup for ns1.oldhost resolves to ns1.newhost's IP, thus fooling the whole system to get its names from there, and thus making everything act as it will after the real DNS switch.

comment Using HAProxy for transparent forwarding and selective redirection
I gave up trying to get haproxy to do this, followed your suggestion and have set up a DNS server with dnsmasq instead, and it works just fine with a 1-line config. I did look at squid, but it's a config nightmare.
