/ must be on a partition or LV that will be formatted. Reusing an existing / is not allowed.

Oh, you said it worked for you.  What version were you testing?

Go to know.

Because ordering affects performance.  For example, I set up a separate
LV "queue" for the mail queue on a mail server; I also have a separate
LV for /usr/local ("usrl", grows to fill the VG, minus space for
snapshots) and /var ("var", where the logs live).  Anaconda orders LVs
alphabetically (last time I checked), which could put the mail queue and
mail logs at nearly opposite ends of the disk.

That covers one option.

I don't necessarily expect anaconda to expand to cover all the available
options, but at the same time, anaconda shouldn't prevent admins from
using the available options via %pre.
