Running genhomedircon creates file_contexts.homedirs but it is pretty sparse:

In the source rpm the file policy/modules/system/userdomain.fc differs between fedora and refpolicy. The refpolicy version just has

I don't see the answer to my labeling problems in the fedora version. Am I missing something? Or is there a different .fc that gets involved in correctly labeling user home directories?

The genhomedircon functionality is part of libsemanage these days, and /usr/sbin/genhomedircon is just a compatibility script that does:
#!/bin/sh
/usr/sbin/semodule -Bn
i.e. rebuild policy in order to regenerate the file_contexts.homedirs file.
So if policy is monolithic, I'm not sure you get any file_contexts.homedirs at all.

hm.. what I can do is a bisect on refpolicy,

It seems the problem was due to the fact that on this particular VM I had neglected to set the selinux user for the unprivileged login (semanage -a -s user_u <login>).

The genhomedircon functionality is part of libsemanage these days, and /usr/sbin/genhomedircon is just a compatibility script that does:
#!/bin/sh
/usr/sbin/semodule -Bn
i.e. rebuild policy in order to regenerate the file_contexts.homedirs file.
So if policy is monolithic, I'm not sure you get any file_contexts.homedirs at all.
