Creating a second /home directory root (/local-home) with apropriate labels?

[Jonathan Abbey]

Hi, folks.

In our laboratory, we have an NIS / automounted NFS environment in
which every NIS user gets placed under an automounted /home.

For one of our users on Fedora 20, I'm attempting to give him an
auxiliary local account whose home directory is mounted under
/local-home/, and I'm trying to figure out how to tell SELinux that
everything under /local-home should be treated analogously to how it
would be treated under /home.

Unfortunately, I've not yet figured out the magic incantation to do
this.

I found /etc/selinux/targeted/contexts/files/file_contexts.homedirs,
and I was able to copy that and sed it with s/\/home/\/local-home/,
after which I could then do a setfiles on my copy to set the
appropriate labels on his existing /local-home/username directory, but
this is obviously just temporarily curing the symptom rather than
fixing the policy appropriately for local accounts going forward.

I expect that there are policy editing tools that I could use to fix
the policy up, for all pre-defined file contexts, but I don't know how
to do that efficiently.

Nor do I know how to arrange things so that third party policy modules
that might be installed later (like for Google's Chrome RPM?) would
inherit the new file_context rules for /local-home appropriately.

Any hints would be extremely helpful.

Thanks,

 Jon
