Finally got the EMF-IX machines booted and they are:

A) Home made cloud init metadata server
B) PXE boot
C) the rootfs is on ATAoverEthernet, and to be fair that's very cool but also looks totally insane on lsblk

If you ever see this outside of EMF-IX, run

# lsblk

Both of those things are my go to quick tests for if the device still works, so if I've not been on one for a while I end up the deeper stages of panic ("oh SHIT did I just blow up the device") before I realise I can just press "a" and see the CLI echo it back...

Can you guess where the code is here? on the outside label? no that would make too much sense, it's inside the device chassis (where the terminal blocks are) and if you can angle your body, hands, flashlight, and mobile phone camera just right, you may be able to see 50% of the code at a time between the air vent grill...

It was surprising to find that there are not really any stable/serious memory safe DNS resolvers, Hickory seems to be littered with bugs (Some not strictly it's fault and more the fact that some DNS Auths do not like QName Minimisation, but from what I can tell has a very spotty situation with DNSSEC

For what it is worth, my general views on DNSSEC's usefulness has not changed (I do not think DNSSEC is "juice worth the squeeze"), but there are compliance situations that force the existence of DNSSEC...

It's just frustrating that the closest to spec-compliance state of the art DNS resolver is Unbound

It's also shocking there is basically no DNS RFC "-bis" document that rolls up all of the (must at least 100) RFCs into a somewhat coherent document, I wonder if the rubicon has been crossed where no one will ever agree on what a RFC -bis would even look like.

Much like the "if your company depends on running other people's x86 code, then Spectre/Meltdown/etc are devastating", I think if your company is/was depending on the user separation boundaries in the OS to work, then you are in a lot of trouble.

[Unauth'd file read/Local Priv Esc]'s have always kind of been low(er) hanging fruit, but they are nowhere near as cool/good at RCEs.

Now that we have machines to find these at reasonable competence and speed, it is probably a good time to look at anything that you run that [processes user supplied data, or speaks over the network] that is written in C/C++ and find memory safe alternatives. It's not those memory safe alternatives are going to be bug free, but they are far less likely to cause you to need to upgrade your kernel every few days to urgently catch up with local LPE's

Even if you are not going to use the new auditing systems for whatever reason, the "enemy" (whether that is your intelligence agencies, ransom gangs, etc) will have no problem trading a few 100$ for what used to cost $10,000's to do.

The sysctls location change being the #1 killer, but there are so many paper cuts in that particular upgrade to keep an eye out for
