# (check to make sure it is "if" defined with "mr") and
# eoe/cmd/initpkg/brc-mr.sh.
# The miniroot filesystem is xfs_growfs-ed in place (in
# eoe/cmd/initpkg/bcheckrc-mr.sh), so it needs to be just
# larger than it's contents, and smaller than the swaplow value.
# These values will need to change as the contents change size.

# longer when the swap space size is changed for the SA.
