I can't tell you about smb, but as for partitions, are you familiar with linux? fstab?
written in another topic by # datech50

using uuid of boot part in /etc/fstab to prevent
the boot drive from automounting. That way the 1GB boot partition won't show up on your desktop.
If you ever need access to the partition you just mount it using diskutility. Just add the line
UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx none hfs rw,noauto 0 0
to etc/fstab

osx doesn't have an fstab file by default so just create one, make sure you set permissions
