Yesterday, i updated /usr/src and proceeded to rebuild world + kernel as
usual on a zfs root install (single disk)
After installing the machine refused to boot with the following error
ZFS: can't find pool by guid
After booting from CD, i first tried to reinstall gptzfsboot, which
worked but did not solve the problem
I had to revert to the (thankfully existing!) zfsloader.old in order to
be able to boot
My disk layout is as follows

The new kernel works ok so far

00:14:13 CLT 2013 root@mbp:/usr/obj/usr/src/sys/GENERIC amd64
Is there anything i can do to help debug the problem?
Best regards,
Roberto
