Yes, it's safe as long and you don't go wild hitting the [del] key in a 
willie-nillie fashion. What I usually do that masks this from all users 
except me is to create the user shares say:


Then for my use I include an additional share for my use only which give me 
root access to all share data; and that also hides the share from all users. 
YMMV, but it works for me.

        comment = Base Samba Share
        path = /home/samba
        valid users = david
        force user = david
        force group = ochiltree
        admin users = david
        browseable = no
        writeable = Yes
        inherit permissions = yes

You are on! Both grand parents lived in Austin. 1807 Pearl, and the other in 
Jonestown on lake Travis. Ahh the days, the hike-n-bike, the lake, chasing 
squirrels with bb guns in Pease Park, Barton Springs (before it was 
topless), Town Lake.....
