How handle rm in pre-service

[realroot2185]

type = scripted
command = /usr/bin/rm -f $XDG_RUNTIME_DIR/bonsai
restart = false

type      = process
command   = /usr/bin/bonsaid -t $XDG_CONFIG_HOME/sxmo/bonsai_tree.json
waits-for = bonsaid-pre
logfile   = $HOME/.local/state/dinit/bonsai.log
restart   = true

Do I need to make a script that check if the file exists before deleting it?
To avoid pre-service failure.

Original service uses superd that has "pre-command" and "on-failure" which can be used to send a notification or something for failed user services.

Hello.

From XDG Base Directory Specification:

$XDG_RUNTIME_DIR defines the base directory relative to which user-specific non-essential runtime files and other file objects (such as sockets, named pipes, ...) should be stored. The directory MUST be owned by the user, and they MUST be the only one having read and write access to it. Its Unix access mode MUST be 0700.

The lifetime of the directory MUST be bound to the user being logged in. It MUST be created when the user first logs in and if the user fully logs out the directory MUST be removed. If the user logs in more than once they should get pointed to the same directory, and it is mandatory that the directory continues to exist from their first login to their last logout on the system, and not removed in between. Files in the directory MUST not survive reboot or a full logout/login cycle.

So there is no need for deleting it on every login.
However something like this could be used for ignoring rm failure:

type = scripted
command = /bin/sh -c "/usr/bin/rm -f $XDG_RUNTIME_DIR/bonsai | :"
restart = false

I experienced bonsai crashing and it was not able to start cause the file was there.
Because the user did not log out.

In command can you use shell-like operations etc.?

To avoid pre-service failure.

"rm -f" doesn't fail if the file does not exist.

[     {X}] bonsaid (exit status: 255)
[     {-}] bonsaid-pre

I thought that {-} meant failed sorry.

I used restart = false because I saw it in dbus-pre service.
To have it executed it every time before bonsaid service can I simply set restart to true?

You should create a script for bonsaid service which does the remove trick on every startup, Something like this:

#!/bin/sh
/usr/bin/rm -f $XDG_RUNTIME_DIR/bonsai
exec /usr/bin/bonsaid -t $XDG_CONFIG_HOME/sxmo/bonsai_tree.json

No way to trigger the pre service restart therefore?

What the location of user scritps folder?
/etc/dinit.d/user/scripts and ~/.config/dinit.d/scripts?
