Adding pre-command to services

[realroot2185]

I am using dinit for user services in sxmo.
I had to make a script to run /usr/bin/rm -f $XDG_RUNTIME_DIR/bonsai before running the process #409.

After I made a bunch of pre-<service>s where the <service> has

waits-for       = pre-<service>

to run pkill <command> because sometimes after logging out the process was still there e.g. lisgd.
Or dunst that it is started by something else causing dinit service to fail.
If it crashes or something dinit won't restart it as it is not under its supervision.
In the same way bonsaid could run rm with a pre-service.

Instead a pre-command option in services can do that e.g.:

type          = process
pre-command   = /usr/bin/pkill dunst
command       = /usr/bin/dunst
logfile       = $HOME/.local/state/dinit/dunst.log

The pre-command exit status etc. won't be taken in account.

While I understand that this could be convenient, we're currently in feature freeze (#509) and there are existing ways to achieve the same thing (pre- services, or execute the command via a script).

One day maybe?

Upvoting this as quite an important feature.
Whilst pre-services have their place, a lot of them could be avoided & service scripts could be significantly simplified if a pre-command option was natively available.
Surely workarounds exist (like bash or implementing execline's foreground command into service scripts) & we do use them in antiX, however I'd personally consider the lack of this feature a key missing component in dinit (for what it's worth)
