This should actually be:

mount -t configfs configfs /sys/kernel/config

I just sent an email off-list with the various wiki pointers to tcm_loop
for local SCSI LLD device access.

Using the rtsadmin shell is definately the easiest way to configure
target core backends and tcm_loop target ports.  Installing this from
www.risingtidesystems.com/git source is still a bit challenging atm, but
we'd be happy to send you an rtsadmin-frozen build offlist for your own
use.  Please let us know if you prefer rpm or debs.  ;)
