In this case, the mess has been pushed into something else. A typical
init script I'm using looks like this:
,----
| case "$1" in
| start)
| systemd-dance "$0" && exit 0
|
| starting ca-mgmt-client \
| mad-daemon -n chdir /home/$USER monitor -s -n ca-mgmt-client \
| chids -u $USER run-ca-mgmt-client
| ;;
|
| stop)
| monitor-ctrl ca-mgmt-client stop
| ;;
|
| restart)
| $0 stop
| $0 start
| ;;
|
| *)
| printf 'Usage: ca-mgmt-client start|stop|restart\n' >&2
| exit 1
| ;;
| esac
|
| exit 0
`----
[That's even with systemd support as I'm meanwhile forced to support it
professionally.]
There's little point in splitting this tiny bit of code into separate
files just because that's technically possible.
?
The historically accumulated mess in Linux init.d scripts is/ was indeed
fairly gruesome. But that's just an example of poor programming/
software design and in not way tied to the arrangement used for running
such scripts at certain times. Thus, the main argument of the
Poetterclown was that "Look what a mess you've made of the stuff you've
put into your old shelf! You absolutely need my New And Very Much
Improved Shelf[tm] because of this!"
