Your solution would work perfectly for me but I still have a doubt:

I think that changing db_root is not allowed if we have a fabric driver loaded
because the latter could have potentially used the core's dbroot
attribute to access the
directory's content.
See the description of the commit that introduced the configurable dbroot:
--------
commit a96e9783e05851d5f06da0ae7635aec55a228e3d
Author: Lee Duncan <lduncan@xxxxxxxx>
target: make target db location configurable
This commit adds the read-write attribute "dbroot",
in the top-level CONFIGFS (core) target directory,
normally /sys/kernel/config/target. This attribute
defaults to "/var/target" but can be changed by
writing a new pathname string to it. Changing this
attribute is only allowed when no fabric drivers
are loaded and the supplied value specifies an
existing directory.
Target modules that care about the target database
root directory will be modified to use this
attribute in a future commit.
