/proc/ is not mounted, but required for successful operation of systemd-tmpfiles. Please mount /proc/. Alternatively, consider using the --root= or --image= switches.

---> Jails are FreeBSD's containers. Jails runs a FreeBSD native app in an
isolated container. You cannot run Linux in a jail. Linux is an OS in its
own right. It does not run under FreeBSD. You can run Linux in a bhyve VM
but not in a jail.

This is what I'm doing right now. I've enabled linux_enable="YES" in
rc.conf :

/etc/rc.conf :
linux_enable="YES"

and I've mounted the following mount points inside the jail and I'm running
Ubuntu 24.04 with the Linuxulator without problems.

nano /etc/jail.conf.d/noble.conf

    mount += "devfs            $path/dev                devfs           rw
                     0       0";
    mount += "tmpfs            $path/dev/shm            tmpfs
rw,size=1g,mode=1777    0       0";
    mount += "fdescfs          $path/dev/fd             fdescfs
rw,linrdlnk             0       0";
    mount += "linprocfs        $path/proc               linprocfs       rw
                     0       0";
    mount += "linsysfs         $path/sys                linsysfs        rw
                     0       0";
    mount += "/tmp             $path/tmp                nullfs          rw
                     0       0";
    mount += "/home            $path/home               nullfs          rw
                     0       0";
    mount += "/root            $path/root               nullfs          rw
                     0       0";
    mount += "/var/run/user/   $path/run/user/          nullfs          rw
                     0       0";
