I files a bug on this a while back and discussed it on this forum, but I
can't seem to find that discussion anymore.
Here was my bug report:
The Leopard Installer will skip the "Destination Select" pane even when
there are multiple volumes that can be selected. It will go straight
from the License pane to the "Installation Type" screen. If you then
press "Change Install Location", it will go back to the "Destination
Select" pane where you can see and select all the available volumes.
After pressing Agree on the License screen, you should be taken to the
"Destination Select" screen when there are multiple volumes to choose from.
Instead, "Installation Type" is displayed not giving you the opportunity
to select a volume.
Notes:
I had some discussions with a couple of Apple engineers about this
issue. It is a "feature" that "Destination Select" is skipped if there
is only one volume to choose. But there appears to be a bug that causes
it to skip that screen when there are multiple volumes. From my
observations, what's happening is that the Installer caches volume info,
even across multiple app launches. On the first launch, when it has to
cache the volume info, it works correctly in that it does not skip any
steps in the Installer. But on subsequent runs, the fact that the cache
is present seems to trip up the Installer's logic, and it skips
"Destination Select" entirely. If you wait until the cache is cleared
(and I'm not certain what triggers that, time seemingly being one of
them) then Installer goes back to working correctly.

This is really weird. I have an installer plugin that runs after
the standard Target pane. First time I run the installer,
everything works normally. The second time I run the installer,
after agreeing to the license agreement, the menu (at left) jumps
right past the Target pane directly to my plugin name, but the
main display is stuck on the License Agreement pane.
Anyone seen this?
A note - this happens to me but I have multiple drives on the
system. Another person who has only one drive doesn't experience
the problem.
Found it!
Seems the second time the installer runs, the installer is skipping
the Select Destination pane and jumping directly to my plugin. But
it does this without setting the targetVolume member of the parent
section.
My installer plugin code assumed targetVolume would be set, so my
code was throwing an exception. In Obj C, this doesn't result in a
crash, so the installer app just froze up on the previous pane that
was visible, which happened to be the License Agreement.
I don't know why this happens, and only on 10.5.
Is your package set to install only on the root volume?
No, I had turned that option off - but I did it via the Info.plist,
rather than rebuilding the package (using Iceberg). If it's stored in
there elsewhere, then it could possibly still be turned on. Even if it
is on, it still goes to the Select Destination pane the first time an
installer is run after logging in or rebooting. And it always goes
there if my installer plugin is not in the package! Weird!
