SELinux and ReiserFS

As I understand it, Hans Reiser has indicated that he will only accept 
bugfixes for reiser3.  It is therefore very unlikely that anyone could 
come up with a patch which would be merged upstream.  Reiser4 will 
support file metadata from the beginning, but of course it's not 
available yet.

I realised, though, that I don't really need to build a custom kernel. 
All I need to make is one module ("sereiserfs") which I then load into 
the normal kernel.  I should be able to build that using the normal 
RedHat kernel source plus the SuSE patch.

Assuming it works as expected, I'll announce it here for the benefit of 
anyone else who wants to use reiserfs.  I'm unlikely to build it until 
FC2 is actually released though.

So is the idea that the whole filesystem gets the same label?  That 
sounds useful in some circumstances, but building a new reiserfs module 
is more *fun*. :-)
