It wasn't because I wanted to, I can tell you that. :)

I'm struggling to come up with a nice easy way to take the package 
basename, and say "OK, find the rpm package with the same base name, and 
install it." This has problems, because all of the different kernel 
packages have the same basename, as do the glibc{i386,i686} packages.
For example, saying install kernel*i386.rpm looks promising, except that 
it will install the kernel, the kernel-headers, and kernel-pcmcia 
packages. The same holds true for similar names. "file" comes to mind, 
which matches file, file-utils, filesystem, rootfiles, audiofile...

When the rpm files are available locally, this is ugly, but fairly easy 
to do. Here's the nasty looking little section of script:

RPM_PATH="/mnt/cdrom/RedHat/RPMS/"
CUT="cut -d "/" -f 6"
RPM_COMMAND="rpm -ivh --nodeps ${RPM_PATH}"
RPM_TEST_COMMAND="rpm -qp --qf "%{NAME}""

for package in `cat /root/scripts/base_packages`
do
    candidates1=`ls $RPM_PATH$package* | $CUT | grep i386`
    candidates2=`ls $RPM_PATH$package* | $CUT | grep noarch`
    candidates=`echo $candidates1 && echo $candidates2`
    if [ -n "$candidates" ]; then
       for match in `echo $candidates`
       do
          test_match=`"$RPM_TEST_COMMAND" "$match"`
          if [ "$test_match" = "$package" ]; then
             "$RPM_COMMAND" "$match"
             if [ $? -ne 0 ] ; then
             echo "Error reported while installing $match."
             echo Error reported while installing\
	         $match. >>   /root/scripts/install_log
             fi
          fi
       done;
    else
       echo "OOPS! Failed to locate $package."
       echo Failed to locate $package. >> /root/scripts/install_log
    fi
done;

Adding ftp and http support to the script required some additions, which 
still worked fine, but for each package, the installer had to connect to 
the server to run the querry, then connect again to download the matching 
package. It seemed like a lot of added bandwidth, so for the moment, I 
removed it. I do intend to add it back, and if anyone has better ideas on 
how to accomplish this, I'd love to hear them.

Also, to accomplish this, the installer needs a directory listing from 
the server, and the stripped down 'wget' from busybox doesn't create a 
directory listing when pointed at a directory like the full wget does. 
Additionally, you can't say: "rpm -ivh http://{server/path/kernel*" 
You have to supply the full filename.
This means the user would have to obtain a directory listing and copy it 
to the floppy, transfer it, etc. It was getting too complicated.

I'll add that, thank you.

I did include a file called COPYING, with the text of the GPL in the 
directory with the scripts.
