Installing Gentoo on ZFS. How?

Question

linux

Salute comrades!
Recently, I've been experimenting with installing Gentoo on ZFS. I'm installing with systemrecuecd with built-in support for zfs. Creating a pool and slicing fs is not difficult, installing the base system too. For my own peace of mind, I looked at the instructions from Funtoo . And at the most crucial moment, after installing packages with zfs, when I try to make zpool status, I get the message
"the /dev/zfs device is missing and must be created/ Try running 'udevadm trigger' as root". And, accordingly, grub also sends me when trying to generate a config.
But the /dev/zfs device itself is present.
Comrades, who can prompt on this issue?
