Ok, everything seems to build and boot fine, logging works too.

Just a minor nuisance: I have this in the log:

...
[   10.498422] console [bcon0] enabled
[   10.499899] blockconsole: now logging to /dev/sdc at 1
[   10.594791] usb 5-2: new full-speed USB device number 3 using ohci_hcd
                                                                                                                                
[   12.665911] xhci_hcd 0000:00:10.0: xHCI Host Controller
[   12.668469] xhci_hcd 0000:00:10.0: new USB bus registered, assigned bus number 6
...

which doesn't have the empty line with a bunch of '\s' chars:

...
[   10.498422] console [bcon0] enabled
[   10.499899] blockconsole: now logging to /dev/sdc at 1
[   10.594791] usb 5-2: new full-speed USB device number 3 using ohci_hcd
[   12.665911] xhci_hcd 0000:00:10.0: xHCI Host Controller
[   12.668469] xhci_hcd 0000:00:10.0: new USB bus registered, assigned bus number 6
...

Do you know per-chance why that happens? I have a couple more lines like
that further in the log file which bcon_tail generated.

Thanks.
