Anyone using zfs on Gentoo laptop?
If so whats your setup like?
Are you using GPT partitions?
Dual boot with Grub?

Two NVMEs, both with GPT, and two partitions. First partitions are 1GB ESP in mirror mdraid with metadata v1.0, which makes those two partitions looks like regular partitions for UEFI, but Linux is aware this is raid. On ESP there is rEFInd and kernel+initramfs (because rEFInd can't load from ZFS), and UEFI has two separate entries for both partitions. Second partitions are mirrored ZFS.

I do started with zfs-0.6.2
It's one of those laptops with with two disk ports so It has an 128G m.2 and a 1TB 2.5".
So, two 1 disk pools. The small disk is / the big one has /home (datasets for documents, music, etc) and an ext2 boot partition on it. iirc grub didn't support booting zfs at the time of installation. Also have an 8G zvol for swap (yes I know I shouldn't have but I can't be bothered to backup and restore, I use the same amount of zram to get around lockups).
Legacy bios, msdos labels.
