Is this not a bit tricky as in dont we need a way to detect ( introduce 
Bootable=yes in target units? ) if the administrator(s) are linking to a 
non bootable target and error out gracefully as in

Something like...

systemctl set-default nfs.target

nfs.target not bootable target exiting...

Or

Bootable dependency in target not meet
nfs.target not bootable target exiting...

otherwise users/administrators might risk linking to a non bootable 
target, reboot and find themselves with an un-bootable host ( which 
might be easy to deal with locally but not so much remotely )?
