# The only difference between the hier and the run flavors is the default live directory path
# hard coded into the s6-rc utilities allowing their use without passing -l <live_dir>.
# A FreeBSD port should follow the operating system file system layout, but there is a corner
# case where s6-rc replacing base system init system *has* to deviate from hier(7).
# The problem is that s6-rc requires a writeable file system
# (to track service state, bind unix sockets, create named fifos)
# very early in the boot process before FreeBSD used to mount /var and /var/run.
# One way to satisfy this requirement is to mount a tmpfs directly under /.
# The live directory shouldn't be kept on /tmp because this often a small
# file system that could be exhausted by accident breaking s6-rc.
# Adding a small /run tmpfs dedicated to s6-rc solves this problem.
