Description Ed Maste freebsd_committer freebsd_triage 2015-11-24 21:02:40 UTC 
boot1.efi/loader.efi do not work with root on ZFS without hacks like storing the kernel and loader.conf in the EFI FAT partition

Thanks, been waiting to see this.

Interested in testing this out. Using Thinkpad X230.

If I wanted to test this on a USB Key version of the installer, could I just fetch https://reviews.freebsd.org/file/data/xxigv3tkegtefkvmzkko/PHID-FILE-2ictbi3caifzol7xf5fq/D4104.diff, patch my CURRENT /usr/src and build a usb key img?

Does that mean it will work with ZFS + drive encryption via the installer?
