There is a program suite which is called hfsutils, it contains programs as:

       hattrib - change HFS file or directory attributes
       hcd - change working HFS directory
       hcopy - copy files from or to an HFS volume
       hdel - delete both forks of an HFS file
       hdir - display an HFS directory in long format
       hformat - create a new HFS filesystem and make it current
       hls - list files in an HFS directory
       hmkdir - create a new HFS directory
       hmount - introduce a new HFS volume and make it current
       hpwd - print the full path to the current HFS working directory
       hrename - rename or move an HFS file or directory
       hrmdir - remove an empty HFS directory
       humount - remove an HFS volume from the list of known volumes
       hvol - display or change the current HFS volume
 
       hfssh - Tcl interpreter with HFS extensions
 
       hfs - shell for manipulating HFS volumes
       xhfs - graphical interface for manipulating HFS volumes

This is also available for linux.

But with that you cannot really mount a HFS volume into your filesystem.
"hmount" rather means: remember in a text file that on device (partition) /dev/<somewhat>
there is a volume called <volume-name>.
"hcd" means: remember, you last visit <directory> on last volume (you have separate working dirs on
each of the "mounted" volumes).
Etc.
You ALWAYS access the HFS volumes DIRECTLY via the hfsutils (raw i/o on the device).

Since the Mac volume isn't really mounted at some mount point, afpd will never see it.
These utils are solely designed to access Mac HFS volumes via commandline (or wrappers).

I just remember:
The utils mdir, mcopy, etc are the mess-dos pendants for that.
I never had to deal with them. :-)
