Solved How to mount the Linuxulator/Ubuntu partitions stored on a ZFS pool/disk during the booting.

[ZioMario]

Hello.

On my disks I have a little of space to store the /compat/ubuntu2310 directory. I must put them to a ZFS disk,specifically here :

/mnt/zroot-133/A_FILES/Backup/FreeBSD/compat/ubuntu2310/

I want to understand how to mount the ZFS pool "zroot-133/ROOT/default" as soon as possible. I've added it to my fstab file,that now it looks like this :

Solution :

/etc/rc.local :


#!/bin/sh
 
zpool import -f -R /mnt/zroot-133 zroot-133
mount -t linprocfs linprocfs /mnt/zroot-133/Backup/compat/ubuntu2310/proc
mount -t linsysfs linsysfs /mnt/zroot-133/Backup/compat/ubuntu2310/sys
mount -t devfs devfs /mnt/zroot-133/Backup/compat/ubuntu2310/dev
mount -t tmpfs tmpfs /mnt/zroot-133/Backup/compat/ubuntu2310/dev/shm
mount -t fdescfs fdescfs /mnt/zroot-133/Backup/compat/ubuntu2310/dev/fd
mount -t nullfs xxx /mnt/zroot-133/Backup/compat/ubuntu2310/tmp
