[meta-virtualization] [PATCH] libvirt: switch to use volatile system for directory creation in /var/run

[Mark Asselstine]

libvirt relies on its Makefile's install rules to create several
directories in /var/run/libvirt. The use of ALLOW_EMPTY_ allows these
to be included in the RPM, however, they are cleared out at boot by
the volatile system. This causes issues since the libvirt runtime does
not check for the existence of these directories prior to attempting
to create files in them, resulting in errors. Here we add to the
volatiles allowing the required directories to be created at boot or
when the volatiles are updated.
