Thank you. I used a simplfied version, since I have no logging concerns:
# Precreate the control FIFO
s6-mkfifo -m 0600 $S6_SCANDIR/.s6-svcan/control
background {
if {
# Block until s6-svscan starts reading its control FIFO
redir -w 8 $S6_SCANDIR/.s6-svcan/control
# Do not leak the fd
fdclose 8
s6-rc-init -c $S6_RC_COMPILED -l $S6_RC_LIVE $S6_SCANDIR
}
s6-rc $VERBOSE -l $S6_RC_LIVE -u change session
}
s6-svscan -st 0 $S6_SCANDIR
This is a bit "dirty" because it depends on s6-svscan internal, i.e. it
creates a FIFO named "control" in its .s6-svscan directory.

Using the fifo trick [1]? As a side note, though the s6 documentation
considers it "dirty", similar methods [2] are widely used for process
synchronisation in CSP-style concurrency.
