Not with this cold and without a lot more study of how UML works, but first I want to confirm that you looked at the new 2.6 nonlinear mappings support (mm/fremap.c, sys_remap_file_pages() and friends...) > This is why in TT mode UML is statically linked, it's done so that we must > not understand where libraries are located and remap them, too.

So if I build 2.6.11-rc3-bk? I can fire up SKAS0 mode and run it on an unmodified kernel? If so, I'm happy to test this... (I read Jeff Dike's blog entry on SKAS0, but it didn't really have any implementation details.)
