the labeling procedure

I'm having some problems with some of my filesystem labeling.  I'm running
FC3 with the latest SELinux updates (but not rawhide).

When I run #make relabel, /home gets labeled as default_t.  However, when I
run #/sbin/restorecon /home, /home gets labeled as home_root_t.  This
confuses me, since according to the O'Reilly book both commands refer to
/src/policy/file_contexts/file_contexts.  Where else might /sbin/restorecon
be getting its information from?

Furthermore, I notice that /src/policy/file_contexts/file_contexts does not
contain the string home_root_t.  I suppose that home_root_t comes from the
homedir_template file during the Make process, but then why doesn't #make
relabel correctly label /home?

I also notice that my context/files/file_contexts file is stale.  Doing
#make relabel or #make reload doesn't update it.  Does this file ever get
referenced anyway, since all the relabeling utilities seem to use
/src/policy/file_contexts/file_contexts instead?  If it does get used, who
uses it?  And how can I be sure it gets updated to match

Any help in demystifying the file labeling procedure is appreciated!
