Since label.Relabel ends up calling into selinux.chcon, we should do the check for invalid directories under chcon. This will allow the selinux.Chcon function to also be verified. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

There was a problem hiding this comment.
Will this part bring back the issue you ran into that you were trying to solve in #180?
But some users put homedirectories under /usr, and I see no reason to block them from relabeling.

No the #180 was blocking /usr/*
Now we are just blocking /usr or $HOME not $HOME/*
