Absolute control over where it goes (down to the sector).
An option to label the filesystem.

I'll take suggestions, but I require the capability to override everything.
Also, from time to time a new system will overwrite an old one.
The last customer for the old partition finally upgraded, and
new users of systems of that vintage are deemed unlikely.
Locating the old filesystem+partition by label is the easiest method.
I also take screenshots of gparted.

Filesystem UUIDs are not guaranteed to be unique, either, and duplicates
_do_ happen.  The obvious method of cloning a filesystem (/bin/dd)
duplicates the "UUID", too.  I've done it once by accident, and a
few times on purpose :-)

In general I don't understand why the graphical parts of the installer
aren't just an app whose output is a kickstart file, and the actual
install is just an execve() with the kickstart file as its only input.
