Here is just an example script (CAUTION: not well-tested) to create a
filesystem/swap with mdconfig(8). This script support not only '/tmp
by mdconfig(8)', but also replaces 'swapfile' variable of rc.conf with
more generic way.
Sorry no diffs for rc.conf(5) nor any comments of this script, but
seeing is believing:)

# mdconfig_tmp_type='swap'
# mdconfig_tmp_size='32M'
# mdconfig_tmp_newfs_enable='YES'
# mdconfig_tmp_newfs_flags=''

# Note:
# - No support of 'mdconfig -u unit'.
# - No error checking of mdconfig(8).
