Solved /etc on a zfs dataset

H

Hello

I installed FreeBSD on a ZFS root and made /etc a separate dataset, which resulted in a not booting machine.

Code: 
cannot open /etc/rc: No such file or directory

Is there any way to tell FreeBSD/zfs to mount /etc at once, or am I forced to move /etc to the default dataset?

It needs to be on the root filesytem as that's the only filesystem that's mounted when the system boots.
 
Additionally, the default layout is boot environment friendly and having the <pool>/ROOT/default dataset contain the /etc directory ensures it matches and provide a cohesive system with the rest of the boot environment.
 
For similar reasons you must have a /boot directory on the filesystem that is used for booting because the bootcode (both UFS and ZFS bootcode work the same way) will be looking for the /boot/loader binary from that filesystem.
