  Looks like this is asked for over and over again, so I think it is 
really worth adding this option. I think this was in fact briefly 
discussed at the BR Developer Days but I didn't write it down in the 
report...

  Between this patch and Richard Braun's, I think this one is closer to 
how it should be.

  One comment below, though.

  This is a bit confusing, because the 'local' site method will force 
LINUX_VERSION to "custom". So I would call it custom here as well.
