[virt-tools-list] [virt-manager PATCH 01/12] util: Add {make, get}_unattended_cache_dir()

[Fabiano Fidêncio]

The "make" method will help to create a "unattended" dir based on the
virt-install process id, so we can store unattended installations
related files without the possibility of another process overwritting
the files.

The "get" method will help to clean up the dirs created by the "make"
method.
