Hiya Arch folks - So I'm working on an encrypted disk setup (dm-crypt + LUKS) for my laptop and have run into some troubles with the USB bootstick I'm using. Specifically, I'd like to use a h/w-encrypted USB stick, with manual keypad unlock, as my boot partition, and also as storage for the other disks' keys.
I'm able to boot just fine from the USB stick, grub starts & launches the init process, but then when udev starts up it not only unmounts the USB stick, it completely disconnects the USB device. This causes the USB device to lock itself, then requiring another keypad entry of the passcode. Of course, by the time the passcode is re-entered, LUKS (at least I think it's LUKS) has timed out and demands a password to unlock the root volume.
I have been able to get this setup working with a non-encrypted USB boot stick. But that also defeats the purpose of encrypting my drives in the first place.
Is there a way, perhaps via mkinitcpio, to prevent udev from re-initializing the USB device? If the device isn't re-initialized and remains unlocked, I'm pretty certain it'll behave like the non-encrypted USB device, and unlock the root volume as expected.
Thanks in advance!
