You might as well write paranoid instead of allergic. Because many 
on this list expect that libsystemd0 is a temporary facility given for 
people the time they migrate to systemd and to seem harmless to upstream 
developpers. Some day they'll decide to withdraw libsystemd0 and 
paranoia/allergia will turn to have been realism. The trap is so visible!

     Call me paranoid :-)
