I'm still not persuaded that it's the right approach.

I.e., let's say we have a device which is always in use, but we want 
tgtd to use it.

With current approach, we have to start tgt-admin several times:

1) Lets start all targets:

# tgt-admin -e -v
Adding targets...
Skipping device /dev/blah, is in use...

2) Configure the device once again, with --force:
# tgt-admin --update iqn.2008-08.com.example:some.target --force

It is not very user-friendly.

Therefore, an option in the config file would be great, like:

	allow-in-use yes
