I saw that option but _want_ to be able to be root on my Samba shares.
It's a single operator machine.

Thanks very much for your excellent suggestion Adam.
I found out the new file created by your touch command was owned by
lba:users. That was expected since I was in a shell as user lba.
However, when I tried to copy over a root owned file, first as su and
then as su -, the operation failed. Why can't I copy over a root owned
file when I'm root?
I also noticed that, when I touched as su or su -, I could create the
file but in each case owner was lba:users. However, when I did the same
touch within my own file system, the file owner became root.
I smbmounted the share with a simple _root_ script containing:
smbmount //tillie/all /mnt/tillie -o uid=0
Shouldn't that have given me root priviledges?
Which leads to the question, how do I act as root on a samba share?
Or perhaps the question is how do I become root on the share?
Is sharing as root okay or is it bad practice? Why?
I appreciate your helping me very much. You can see I'm a little
confused how to take over my little network and bend it to my will <g>.
