Firstly sorry for the bad thread title. I'm not sure how to summarize my issue.
I have to alter a legacy automated build process which uses a FreeBSD 11.0 virtual machine.
When I run the virtual machine image in Virtualbox I can log in and see the following zpool, zfs, mount details:
I have been able to mount the vm disk image, from linux, using the following commands.
I can see the following disk, zfs file systems and mounts.
The problem is that I need to access files in /root/mnt/etc but the / partition is not mounted.
How can I do that?

Welcome to fdisk (util-linux 2.35.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
The device contains 'zfs_member' signature and it will be removed by a write command. See fdisk(8) man page and --wipe option for more details.
