\ config-string-with-value-reset creates a config-variable like as 
\ config-string.
\ Additionally, setting value into the created config-variable results in
\ resetting a value specified by the config-variable definition.

\ e.g.
\
\  ' #faults " disk net" d# 256 config-string-with-value-reset boot-device
\
\  In this case, boot-device setting results in resetting #faults.
