# The following shouldn't be necessary. UEFI defines a way to
# specifically select what to boot (which we do via
# efibootmgr). However, virtual environments often times lack
# support for the NV variables efibootmgr sets. In addition,
# some UEFI implementations have features that interfere with
# the setting of these variables. To combat that, we install the
# default removable media boot file as a fallback if it doesn't
# exist. We don't install it all the time since that can
# interfere with other installations on the drive (like rEFInd).
