Hi.

So, I'm still struggling with my problem when I cannot boot from a big
zfs 2T pool (I have written some messages about a year ago, the whole
story is too long and irrelevant to retell it, I'll only notice that I
took the path where I'm about to boot from a separate zfs pool closer to
the beginning of the disk).

I've created such a smaller pool, called it zboot. I've read pjd@ letter
explaining that when FreeBSD sees several bootable pools, it chooses the
first one - that's fine with me, since the new pool partition's number
is smaller than the big one. So, I created zboot, set the mountpoint to
legacy, wrote the content to it's /boot directory (and yes, I did call
the 'make installkernel DESTDIR=/zboot') and rebooted. Strage thing
happened next - I got


Can't find /boot/zfsloader

FreeBSD/x86 boot
Default: zboot:/boot/kernel/kernel
boot:
|
Can't find /boot/kernel/kernel


I booted back from USB stick (that I'm using to boot my machine) and
rechecked these files - everything mentioned here is in it's place.

Does someone have the idea what I'm doing wrong ? May be this has
something to do with the fact that zboot does contain only the /boot
directory, and not the full rootfs ?

Thanks.
Eugene.
