comment How do I tell which device tree blob (dtb file) I'm using?
Thanks. bootcmd being the one env variable that contains the initial startup script was what I needed.

comment How to quote the quote marks in strings in u-boot?
Actually, the comparison without quotes works, but I'd still like to know how to get these quotes in.

comment How to quote the quote marks in strings in u-boot?
@terdon: The original string uses single quotes there, It's exactly what I wrote I wanted to put in there. Maybe I can get double quotes in, but that's not what I want; I want to restore the original. I can give the actual results for the rest...

Should I add the 'scrub' after each boot-up as well?

comment Why do I need to mount a USB flash drive if it's already in my Raspibian
As others suggested, if you want the drive always mounted on startup, just add its entry to fstab, and it will be mounted automatically every time the system starts. Don't confuse startup automount (fstab) with the Automounter - runtime detector of new drives which mounts them as required. Automounter is a very tricky (and still, good two decades in development, unreliable) thing to configure/modify. If it works, enjoy that it works. If you see contents of the drive, it's (most likely) mounted.

More importantly, probably the drive is NOT mounted until you open some file manager to display available drives. I don't know enough about Raspbian, but for example, Kubuntu automounter does this - there's nothing in /media/ until you open a graphical file manager like Dolphin.

comment How to restrict/cut power output to a USB client?
That's why/how I hoped this could be done: I read there's a 'power negotiation' phase between the device and the host, and the host can decline high power requests. But I never learned what happens when it does. I hoped the phone would advertize at least two configs: 'charging' and 'communication'... I still wonder what happens when the exchange goes like: Device: "I demand 500mA". Host: "Okay, here's your 5mA" (e.g. host agrees to exorbitant request, then fails to deliver.)

comment How can I get a vfat pendrive to automount as posixovl filesystem?
@MichaelKjörling: I guess the solution would be along these lines but I'm pretty much clueless about udev (and not breaking it for updates etc, as it's probably wrapped in several abstraction layers).

comment Why do we need to mount on Linux?
@Ruslan: Actually, umsdos is obsolete; the modern alternative is fuse-posixovl which acts in even different way: you first mount the vfat partition, then mount the posixovl overlay over it - as if it was a partition, and the vfat system starts acting like a native Linux one. (I picked umsdos as an example because this is the most obvious and simple case where customization of the mount process is useful. Another such case is /dev/loop, mounting files as partitions, e.g. .iso images of cd/dvd disks.)
