Anyway, someone at forums.debian.net asked for it, which got me thinking about making a post:
sudo apt-get install build-essential gfortran checkinstall python-all-dev cdbs debhelper quilt intltool python-central rarian-compat pkg-config gnome-doc-utils samba python-libuser libuser1 python-glade2 mkdir ~/tmp cd ~/tmp wget https://launchpad.net/ubuntu/+archive/primary/+files/system-config-samba_1.2.63.orig.tar.gz tar xvf system-config-samba_1.2.63.orig.tar.gz wget https://launchpad.net/ubuntu/+archive/primary/+files/system-config-samba_1.2.63-0ubuntu5.diff.gz gunzip system-config-samba_1.2.63-0ubuntu5.diff.gz patch -p0 < system-config-samba_1.2.63-0ubuntu5.diff cd system-config-samba-1.2.63/ dpkg-buildpackage -uc -us sudo dpkg -i ../system-config-samba_1.2.63-0ubuntu5_all.deb sudo touch /etc/libuser.conf gksu system-config-samba
And here we go:
i.e. it at the very least reads my /etc/samba/smb.conf accurately.
To make system-config-samba show up in your gnome menus, add it via Main Menu. Make sure to include gksu in the command to launch it.
