# When a new snapshot gets released, a setrelease request is sent to OBS.
# It does $nbin =~ s/-([^-]+)(-Media(?:\d?)(?:\..*?)?)$/$setrelease$2/;
# which basically replaces -Media* with the Snapshot number.
# The isos written by KIWI (and subsequently renamed by the OBS KIWI
# build recipe) do not follow that name scheme, so we need to rename
# it manually to the expected names.
