This is where theory goes vs practice I guess. Theoretically uml will not 
meddle with the rest of the kernel. I think that would even break the concept 
which it is based upon. But in practice? I don't know. I have not yet seen 
the future UML-patches. I think there is a 99.999% chance that the patches 
are "compatible".

The nice thing about this is that only uml-specific code needs to be patched 
(syscall tables, some constants and config.in et al).

So far, no new files are needed. But I'll keep it mind should I start adding 
new files.

I have some practical suggestions regarding storage of code.
Maybe a sourceforge account would be in its place? I am setting up one myself 
most likely for the patch since my own machine may be down at times for 
various reasons. And also, if the patch becomes extremely popular ;-), my 
work machine does not have to pay the price of increased interrupts for I/O 
and CPU cycles. Ideally, an RSBAC-account would be really nice - where all 
the addons may reside as well. I understand it may be a security risk by 
letting the code reside on a remote server, but you could always supply 
PGP-signatures for each release.

Also, most importantly, people can rate my "Code Fu" ;-)

Anyway, I'll shortly have an "official" patch (give or take a lunch break).
