Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code

They didn't provide the source code with the router.

There is no requirement to put up a download link, but there is a requirement to provide the source code to any third party that asks for it

I stopped working on Ubuntu because decisions were increasingly being made internally rather than anywhere that volunteer contributors could influence them. The "Click here to instantly break your mouse" thing was just the final straw. There's a component to the story that involves beer and a hilarious reply vs. reply all error on an iPhone, but I don't remember it being about anyone siding with Scott - there's a picture somewhere of me deactivating my Ubuntu membership a few minutes after sending https://lists.ubuntu.com/archives/ubuntu-devel/2008-February/025141.html , which hardly gave them time to.

Wubi doesn't support UEFI. Once it does, it can use the same signed bootloader that Ubuntu currently uses.

I'm sorry, you're right - I was under the impression that overcommit_memory defaulted to permissive rather than heuristic allocation. However, overcommit_ratio is also ignored by default.

"Setup mode" is part of the UEFI specification. You can add any keys you want to while you're in it.

You can malloc() as much as you want until you run out of address space. That's 3GB on 32-bit systems, no matter how much RAM you have. Things will only go wrong if you attempt to use it for anything.

Removing the CMOS battery didn't recover this system, which is pretty much what I'd expect - UEFI variables are typically stored in the same hardware as the firmware itself, and unplugging batteries doesn't kill your firmware.

The system doesn't fail to boot. The system doesn't even complete its power-on self checks. The screen is never turned on. It never responds to keyboard input. It's bricked. This machine's not coming back to life without an SPI programmer.

Unfortunately not in this case.

30-day hassle-free return policy.

Yes, but Windows requires signed drivers.

Disabling secure boot means you can easily lie to the OS about whether or not secure boot is enabled.

If it were an anti-piracy measure then there wouldn't be a requirement for you to be able to disable it.

The kernel can execute ring 0 instructions. Your initrd can't. The difference is that you could construct an appropriately modified hibernation image that booted an arbitrary kernel - or even an entirely separate OS. In that scenario, your kernel is effectively a new bootloader, except unlike the signed bootloaders it'll happily boot an entirely unsigned OS. That's unlikely to end well.

But, conceptually, you're right. Secure Boot doesn't magically make a system secure, but it *is* a vital part of system security - if you can't trust your kernel, any other security you attempt to build is pretty much pointless.
