It's not "coming from" Red Hat, Fedora is forked from it originally but is directly downstream from the linux kernel, there's no Red Hat involved between the Linux Foundation and the Fedora devs.

In fact, there's no more Red Hat at all, there's only RHEL, which is downstream from Fedora.

Fedora is not downstream from Red Hat. I don't know how to put that in any plainer terms...

Yeah, that's all there is to it. The finish script is optional, and rememer to make your links. You can have user level services by making links for runsvdir-USERNAME. This creates a service that manages your services.

It could probably be more robustn but here's my setup:

$ readlink {/etc/sv,/var/service}/runsvdir-$USER | sed "s:$USER:USERNAME:g"
/home/USERNAME/.dotfiles/runsvdir-USERNAME
/etc/sv/runsvdir-USERNAME

$ print -l /etc/sv/runsvdir-$USER/*(.)
/etc/sv/runsvdir-USERNAME/conf
/etc/sv/runsvdir-USERNAME/finish
/etc/sv/runsvdir-USERNAME/run

$ print -l /etc/sv/runsvdir-$USER/*(.) | to -b -C '#' -A $'\n' cat | sed "s:$USER:USERNAME:g"
# /etc/sv/runsvdir-USERNAME/conf
#!/bin/sh

set -eu

self="$(realpath "$0")"
root="$(dirname "$self")"
user="$(basename "$root" | sed 's:^runsvdir-::')"
home="/home/$user"

groups="$(id -Gn "$user" | tr ' ' ':')"
svdir="$home/service"
#

# /etc/sv/runsvdir-USERNAME/finish
#!/usr/bin/env sh

set -eu

self="$(realpath "$0")"
root="$(dirname "$self")"

[ ! -e "$root/conf" ] || . "$root/conf"

sv -w600 force-stop "$svdir/"\*
#

# /etc/sv/runsvdir-USERNAME/run
#!/bin/sh

# start up for user-level service configuration

set -eu

exec 2>&1

root="$(realpath "$0" | xargs -d '\n' dirname)"
[ ! -e "$root/conf" ] || . "$root/conf"

exec chpst -u "$user:$groups" runsvdir -P "$svdir"
#

For clarity, the to command is an xargs alternative that's not out, yet.
