Usually if you copy them directly to their destination, they'll have the 
correct context.  If you copy it to a different location first (like 
/home/) and then move it into place, it'll have the context that it got 
when it was created (like user_home_t).

I use bcfg2 to manage configuration files, for instance, and I don't 
believe that any SELinux contexts are broken as a result.

No, it wouldn't, and it's not intended to.  It is intended to confine 
your system daemons so that an attacker cannot overflow a buffer and 
execute arbitrary shell code (for instance).
