Attempting to install 6.1 via ftp to upgrade a 6.0 system
does not work, and produces a stack trace which is quite
tedious to write down and thus is not reproduced in full
here. I've jotted down some highlights of it though, which
are below. Note the extra space after CWD, which I believe
is the culprit.

This is a bug which relates to the structure of the FTP server and path
arguments in the installer. There is a problem which requires that you specify
the FQDN for the FTP server. In addition, you will want to specify the path to
the source files WITHOUT a trailing slash.
So, if you are installing from krusty.redhat.com from the directory
/mnt/dist/6.1/i386, you would want to make sure that you type
"krusty.redhat.com" for the FTP server and "/mnt/dist/6.1/i386" for the path.
Typing "/mnt/dist/6.1/i386/" will result in the error that you quote above as
well as typing just "krusty" for the server name.
