Note workaround for 'No data available'

Browse Source 
In a diskless boot, sometimes the build system
might not label the scratch contents
correctly.  setfiles can be used to fix it.

Notably, this seems to cause the overlay+squashfs to
return 'no data available' on select
calls even with selinux disabled, so it may be another
gap with overlay and/or limitation of squashfs when
queried about modification without a label.
