may i ask why given that vfs_fruit is much newer then netatalk it did
not reuse the existing format of netatalk then instead a changed one
then with a new option adopted by netatalk leading in the current mix?

"dbd" at least should have introduced a command line option to convert
the existing stuff with a onetime run

* close 548 on the firewall
* update netatalk
* add the new option
* restart netatalk
* run dbd with the convert-switch
* open 548 for clients again
* done
