emOS 0.2
Names the device, on the USB descriptor and on the console. Both found on the
first provisioning run to reach a booted emOS device.
The USB console says what it is
The gadget set idVendor and idProduct and no descriptor strings at all, so the
host fell back to whatever it had cached for that port — on a Mac that showed
as "MT65xx Android Phone", left over from the same device in preloader or
FireOS mode. An operator picking a serial port in the provisioning wizard had
nothing to aim at, and tried several before concluding the right one had not
worked. It had.
Now EchoMuse / "emOS console" / the unit's serial, matching what stock sets
(Amazon / AEOBC / serial).
The prompt says which device it is
The kernel default hostname stood because nothing ever set one, so every
console session and log line read root@android — misleading on a device whose
whole point is that Android is gone, and useless for telling two Echoes apart
over USB. Now em-, or plain "emos" if the serial cannot be read.
Set through /proc/sys/kernel/hostname rather than sethostname(2): bionic does
not declare that at API 21, and an implicit declaration in a static PID 1 is
not something to ship. Caught by -Wall in the pinned compiler image, which is
the only place it shows.
The serial comes from androidboot.serialno on the kernel cmdline, which LK
supplies — the only source available, since there is no property service under
emOS and /system carries the build's identity rather than this unit's. Parsed
against the real cmdline plus the absent, empty, end-of-string and overlong
cases; an unreadable serial is treated as unknown and the boot carries on.
Requires a reflash to take effect: this is in the boot image, not the
controller.
