No. The process FreeBSD uses to boot is as follows:
1. Load kernel from disk or other media
2. Kernel initializes various hardware and subsystems.
3. Kernel mounts root file system.
4. Kernel invoked init
5. Init runs /etc/rc and waits for it to complete
6. /etc/rc reads /etc/rc.conf
7. /etc/rc runs various scripts in /etc/rc.d in a specified order
8. Various scripts run including /etc/rc.d/mountcritlocal
9. Init loads gettys specified in /etc/ttys and goes into it's main loop
The order in fstab doesn't matter, the kernel only knows enough to mount
the root fs, and the scripts in /etc/rc.d mount all the other
filesystems, but by then, rc.conf has already been read or attempted to
be read. You could hack /etc/rc to mount another fs, but I would
strongly recommend against it.

I sense much NT in you.
NT leads to Bluescreen.
Bluescreen leads to downtime.
Downtime leads to suffering.
NT is the path to the darkside.
Powerful Unix is.
