Hi Zbyszek,

I understand what you are saying and perhaps I am looking at it from a 
different angle. But the problem with your suggestion is that it is a 
non-generic way to handle it. The 'cryptsetup at encrypt_storage.service ' 
is completely dependent on whatever is listed in the /etc/crypttab and 
that could be changed by the user at any time. If that /etc/crypttab 
entry was renamed or commented out, the dependency would mysteriously 
break. Maybe there needs to be a cryptsetup-begin.target and 
cryptsetup-done.target instead? I don't think its is far stretch to want 
to ensure some happens before ANY encrypted devices has been opened.
