No, a manual clear_config does not reproduce the issue.
here is waht happens:

Please consider that the new initd script fails with or without srpt target. 
Executing sh -x, we found that the parser is correctly loading the appropriate modules, in this case scst, scst_vdisk, iscsi_scst and ib_srpt, but the scstadmin -config /etc/scst.conf fails with that error. 
Please consider too that manual modprobe scst, modprobe scst_vdisk, modprobe iscsi_scst, modprobe ib_srpt, daemon iscsi_scstd and scstadmin -config /etc/scst.conf works just fine. 

Many thanks,

Ok, let me make sure I have this correct. The problem line is the clear_config line, correct? So, if you manually modprobe and scstadmin -config, what happens when you manually -clear_config?
