Subject: [PATCH] osdict: Always return the most generic tree
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From: Fabiano Fidêncio <fidencio@redhat.com>
Some OSes, as Fedora, have variants (which we rely to be standardised on
osinfo-db side), which we can use to return the most generic tree
possible, in case no profile is specified, in order to avoid failing to
install a "Workstation" system because a "Server" variant tree was used.
