As a Mac newbie, it took me a while to get this to working, but I finally have static SMB automounts to my NASLite disks from my iMac (OS X 10.4.6). I used Netinfo Manager in the Applications/Utilities directory, as per the excellent
http://www.bombich.com/mactips/automount.html, but used the following properties:-
name -----> 192.168.100.2/Disk-1
dir ---------> /Network/Disk-1
opts -------> url==smb://NAS-User:@192.168.100.2/Disk-1
vfstype ---> url
Hope this helps anyone who gets as stuck as I was!
