Hah. I booted one of those NUCs from the AI-healthcare company with all the security problems (it wasn't connected to a network!) and it turns out they configured their system to fsck / on EVERY BOOT.clearly they have a LOT of trust in... well, all kinds of things. power supply, system crashes, bad hard drives?

@Skirmisher yeah. it does a full fsck every boot. even after being cleanly shutdown

@foone I have personally done this because the people before me used a normal Linux distro and depended on asking the users to shut the damn thing off nicely instead of pulling the plug out of the wall before wheeling it to the next room. Fsck at boot cut the call volume and the 'fix my device' rate significantly and took very little time to implement and retest.I'd have liked to have fixed it by switching to a read-only root fs, something like yocto for better updates, etc, but time forbade.

the fuckknobs turned off USB-keyboard support in the BIOSwhich means when grub boots I can't select anything. and I can't get into the BIOS to fix it, because guess what? THE KEYBOARD DON'T WORK

or it might be getting confused by this keyboard being too "fancy". maybe it doesn't trigger the BIOS's USB-keyboard support

@foone I had an old ThinkPad T60 that had a borked BIOS that failed to initialize the screen; turns out if you get the dock for it, the serial port on the dock works from very early on and I was able to diagnose things that way.Perhaps there's a different way of talking to it than USB?

I eventually just let it boot to the installer, which made the USB work, since it was a full OS

@foone That scans:Most BIOS don't support full USB-HID; there are a set of standard hard-coded "boot interface descriptors" for keyboards and mice where the device can say "yep, data coming off of me is in that standard format, you don't need to parse my full custom descriptor".Some fancy keyboards don't implement the boot interface descriptor and only implement their own custom descriptor (I know this is true of the Keyboardio Model 01).

@foone edit the firmware and flash it back - I bet the settings are not signed and you can adjust USB keyboard support in the NVRAM area.It might even be that the appliance is just as vulnerable as so many other devices:https://www.binarly.io/blog/efixplorer-hunting-uefi-firmware-nvram-vulnerabilities

whelp. I took it apart to find out what it was: A Qotom Q4200UG2-P.They don't seem to believe in "manuals" or anything like that, so I can't find any info on how to unfuck the bios

@foone Dang, no PS/2 or USB keyboards worked? Strange. Maybe it's one of those fancy mouse driven BIOSes that I hate so much? Though I dunno why a NUC would be like that.

@foone any remote management/lights-out option? I don't see VPro listed as a feature (and the skim I just did of Intel's docs make it sound like Some Work) but that might be an 'in'.

@foone Every time I learn something new about systemd, it's because it has subsumed something else that definitely does not belong in init.
