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

If his directory is going to be a subdir of /local-home Then just do

# semanage fcontext -a -e /home /local-home # restorecon -R -v /local-home

If his homedir is /local-home then you need to get creative

# semanage fcontext -a -e /home/foobar /local-home # restorecon -R -v /local-home

Should get you the correct labels.
