[CFT][PREVIEW] ZFS new SPA

[Martin Matuska]

Hello all,

I have ported the ZFS features support (SPA version 5000) from Illumos
to FreeBSD-current.
What is still missing is boot support - needs to be implemented.

Patch against CURRENT:
http://www.vx.sk/download/patches/freebsd/zfs/head-zfs-features.patch

Amd64 ISO images for testing (bootable, work well in VirtualBox):
Basic: http://www.vx.sk/download/ISO-images/mfsbsd/head-zfs-features.iso
(86MB)
With full installworld:
http://www.vx.sk/download/ISO-images/mfsbsd/head-se-zfs-features.iso (239MB)

TODO: boot support (check feature availability from ZFS boot code)
