# @BLURB: eclass for packages that install files into /boot or the ESP
# @DESCRIPTION:
# This eclass is really only useful for bootloaders and kernel installation.
#
# If the live system has a separate /boot partition or ESP configured, then this
# function tries to ensure that it's mounted in rw mode, exiting with an error
# if it can't.  It does nothing if /boot and ESP isn't a separate partition.
#
# This eclass exports the functions provided by mount-boot-utils.eclass to
# the pkg_pretend and pkg_{pre,post}{inst,rm} phases.
