Hi Miod,

I'd like to try your patch on an XP1000, but I'm strugling a bit because
I don't want to touch the hard drive (sd0) that is currently installed in
the machine (with 5.4-stable on it).
I installed the latest snapshot on a USB stick (sd1), but the machine
obviously can't boot direcyly from it.
When I copy the kernel from sd1 to sd0 I can easily boot, but then of course
it thinks sd0a is the root fs (and panics because it can't run init from
5.4 on a 5.5-current kernel due to the time_t changes).

As far as I know there is no easy way to tell the kernel that the root fs
is sd1a, like giving a boot flag from the SRM console.

Without a running current system, I can't compile a kernel with the patch.
So what are my options, besides putting another scsi disk in the machine?

If you can send me a bsd.rd with the patch, I can try to boot it and mount
the USB-stick (or even install the latest snapshot on it, to end up in the
same state as I'm in now, but then at least I can test the working of the
USB system).
