Can't share "/mnt/volume"

[Ron Smith]

I'm not sure I completely follow this thread, so I am going to give my 
answer with the following assumptions (because I *think* this is what 
you are trying to do): you want to have and HFS partition (/dev/hda2) 
automatically mount to /mnt/Stuff when the system boots.

To do this you need the following entry in your /etc/fstab:

/dev/hda2		/mnt/Stuff		hfs		defaults

After fighting for a while trying to mount an HFS partition the "right" 
way and using the numbers at the end of the /etc/fstab entry I have 
been unsuccessful every time. As soon as I left them out, it started 
working every time. I think that someone mentioned using chmod 777 for 
your mount point and that is a very good idea, as a place to start. 
Once it starts working you can try and tighten up security on it, 
although in many instances those can be overridden by the entries in 
/etc/fstab, so even if you have really tight permissions on it, if the 
/etc/fstab entry has noauto,users,rw   it will open the mount wide open 
to all users. =)

Good luck,

-Ron
