Thanks, going through that now.

A few questions:

Where is the "default kickstart template"?  I thought it would be
/var/lib/cobbler/kickstarts/default.ks, but "$kickstart_start/_done"
doesn't appear in that file (or any file in /var/lib/cobbler/kickstarts/)

There are several references to $SNIPPET('kickstart_start') in those
files, but nothing to $SNIPPET('kickstart_start')/done or
$kickstart_start/_done

In any case , as Jack Peterson mentioned, there appears to be a SELinux
issue.  I ran setroubleshoot:

    Apr 12 13:58:24 GS-444-E10285 setroubleshoot: SELinux is preventing
    /usr/bin/python from write access on the directory
    /var/www/cobbler/rendered. For complete SELinux messages. run
    sealert -l 528b9bb7-e539-4d67-a82a-c89fb7fbc01e
    [root@GS-444-E10285 cobbler]# sealert -l
    528b9bb7-e539-4d67-a82a-c89fb7fbc01e

    directory /var/www/cobbler/rendered.

    If you want to fix the label.
    /var/www/cobbler/rendered default label should be cobbler_var_lib_t.
    Then you can run restorecon.
    Do
    # /sbin/restorecon -v /var/www/cobbler/rendered

    If you believe that python should be allowed write access on the
    rendered directory by default.
    Then you should report this as a bug.
    You can generate a local policy module to allow this access.
    Do
    allow this access for now by executing:
    # grep cobblerd /var/log/audit/audit.log | audit2allow -M mypol
    # semodule -i mypol.pp


The directory /var/www/cobbler/rendered doesn't exist -- where'd it go? 
I looked on my another test server (which still has cobbler 2.0) and the
rendered directory exists -- did updating to 2.2.1 delete it?

In any case, since /var/www/cobbler/rendered didn't exist I couldn't run
restorecon -- so I did the obvious:
    - created /var/www/cobbler/rendered
    - ran /sbin/restorecon -v /var/www/cobbler/rendered

Then I started cobblerd successfully.   I also restarted httpd.

Now Iwhen I try to login to the web interface, the browser reports
"Internal server error"; setroubleshoot shows I'm getting SELinux errors
on the sessions:

    Apr 12 14:48:54 GS-444-E10285 setroubleshoot: SELinux is preventing

    /var/lib/cobbler/webui_sessions//


I tried running restorecon on /var/lib/cobbler/webui_sessions/ but this
did not resolve the login issue.

I also tried running the SELinux-related commands from cobbler check:
    # /usr/sbin/semanage fcontext -a -t httpd_sys_content_rw_t
"/var/lib/cobbler/webui_sessions/.*"
    # /usr/sbin/semanage fcontext -a -t public_content_t
"/var/lib/tftpboot/.*" && /usr/sbin/semanage fcontext -a -t
public_content_t "/var/www/cobbler/images/.*"

(NOTE:  there is an error in the "cobbler check" output, the quotes are
in the wrong place:
/usr/sbin/semanage fcontext -a -t public_content_t
"/var/lib/tftpboot/.*" && /usr/sbin/semanage fcontext -a -t
public_content_t "/var/www/cobbler"/images/.*
)

In any case, that did not resolve the login issue.  Any ideas?
