I don't think it would be enough parts that the machine would fail though.
Surely most of userland is not dependent on the kernel.

Is it really enough to keep you from fixing things?

Of course, if you are going to play with -current, you shouldn't really
be dependent on that machine anyway, or at least not the drive you are
using for -current.
