Interesting. For anyone interested in this, I've reimplemented dsd's
trick on chvt.pyx so it doesn't affect us anymore. The upcoming 8.2.2
has the fix.

For the F11 trac, dsd's was going to merge the fix into
modules-dracut-olpc to keep things consistent, even though that
codepath is now only hit on boot, and there's AFAIK nothing to race
against.

Not sure what handles the shutdown-time VT-switch to the ul-warning,
but dsd sounded confident that it's not racey.
