Frank,
Thank you very much for finding the bugs! I'm surprised that they haven't
come up before. But then again, not too many people acutally use the
kernel_picker and I can debug just so many setups here.

As a 'quick fix', I have added a command line option to kernel_picker
called '--autoselectimage':
In the event that there are two or more OSCAR image directories
but you do not want to have to specify one via the '--oscarimage'
option (e.g. when you want to call kernel_picker from another
program), use this option. (The first OSCAR image directory,
alphabetcially ignoring case, will be used.) Otherwise, you will
be presented with a list of OSCAR image directories and be asked
to choose one to use.
This will at least make post_clients work without pausing for user
interaction.
I think another possible solution is to display a list of OSCAR images in
kernel_picker's Configurator and make the user choose one. That shouldn't
be too difficult to add to pre_configure. I'll look into it. If the user
doesn't want to select an OSCAR image (for whatever reason), kernel_picker
can still use the '--autoselectimage' option, so I think it's a useful
command line option to have.

Thanks for finding that one. I have added it to kernel_picker.

I have uploaded the changed files to CVS (which you can get from the OSCAR
project page at http://sourceforge.net/projects/oscar/) and I have also
posted the latest version of kernel_picker on NCSA's OSCAR page at
http://oscar.ncsa.uiuc.edu/ . Both an RPM and a tarball are available.
Thanks again for the help and please let me know if there are any problems
with the changes I made.
