Wanting to make a note for the future in case this happens again,
I have written :

  Hostname set by  /etc/init.d/hostname :
    the binary  /bin/hostname  is provided by Net-tools + USE="hostname" ;
     hostname  needs to be set to  localhost  to make apps work properly :
    this is done via  /etc/hosts ,
     wh belongs to Baselayout & shd contain '127.0.0.1 localhost' ;
    there is also  /etc/conf.d/hostname ,
     wh belongs to Openrc & contains 'hostname="localhost"'.

However, I'm now wondering whether/why the system needs both
 /etc/hosts  +  /etc/conf.d/hostname , which seem to do the same thing.
Can anyone explain ?
