Mirrored Installation w/ slices = Failed

[LinuxTracker]

Latest version of 2.0.1-Release x86.
I'm trying to partition and mirror a drive during install.  It errors right at the end of the drive setup, and prior to file copy.

I'm guessing I've hit a bug, but I thought I'd throw it out there.  Maybe someone has a workaround.

FYI: I'm having the same problem as the user in this thread:
http://forum.pfsense.org/index.php/topic,49671.0.html

Execution of the command

cd / dev && / bin / test-pfSenseMirrors1e | | /bin/sh MAKEDEV pfSenseMirrrors1e

Failed with a return code of 2.

The relevant line in the log is:
MAKEDEV: Can't open MAKEDEV: No such file or directory.

My understanding is the MAKEDEV script is no longer included in the later versions of FreeBSD.

I'm partitioning off /var and /usr, based on marcelloc's experience in this thread.

(He implements machine redundancy instead of drive redundancy, so he hasn't personally run into this issue.)

My thanks for any/all advice.

Why not just use the gmirror option in the installer to make a mirror for you?
