I took the /boot/zfsloader file from another box running 10.1-STABLE #0
r275391 built on Dec 2, 2014 to the box with 10.1-STABLE #0 r275828 -
won't boot, same error message. However, /boot/zfsloader from
10.1-STABLE #0 r275828 does boot 10.1-STABLE #0 r275391.

So, I have this:

Box #1: 10.1-STABLE #0 r275828 amd64, built on Dec 16

/boot/zfsloader
SHA256 (/boot/zfsloader) =
12ad6a59082fa4639f3f991319892259b1777b26b28c8aa09c2b53d0326d3b33
- Does not boot Box #1
- Does boot Box #2

/boot/zfsloader.old
SHA256 (/boot/zfsloader.old) =
b5530ce9f9128949b44384516974ba4ef741e587975e3e1d71933798150502e3

Box #2: 10.1-STABLE #0 r275391 amd64, built on Dec 2

/boot/zfsloader
SHA256 (/boot/zfsloader) =
1e3d692dc53c5e0ddeb75b8a453a0a44cbf4c97bc8cfe02b0ad45928374f4718
- Does not boot Box #1
- Does boot Box #2

Would you please advise?
