Trying to make a couple of applications rerun when updating, but making sure those applications have $EUID different from root
#User hooks for pacman

So, whenever pacman updates some systemd-bus related packages, some applications that I run in userspace that depend on it breaks, mostly fcitx5 and some mouse configurations
I have a couple of scripts that I use on my i3wm configuration that takes care of fixing the mouse issues, and fcitx has native support for "reloading"
the thing is, both apps are ran as my user, so I'm mostly just brainstorming to see if there is a way to make it so that "user hooks" are possible

you could probably add a system hook that runs a script which does something like su $SUDO_USER -c "commands to reload the app as a user"

it doesn't look like there's a way to tell it to run the hooks as some user

oh maybe

I don't mind writing applications
I could possibly make a root app that takes a look at the config for available users and their hook directories
which could then run that su command

this only works if you are running sudo pacman [...]
SUDO_USER would then be your user
you could also just hardcode your username in the script

I don't think that'd be an issue unless the user hooks must always be rerun regardless of who is current logged in
the thing with these "user hooks" is that they only need to be run when the session owner is the user
so, technically not a bug, just a feature
sick cave
you could just check the username in the script

I think unless rerunning these apps would be more trouble if they don't have to be rerun it's probably easier just to run a script after updating

I wonder if I can make something generic that works for everyone
or rather, mostly everyone
sick cave
a user hook system should be relatively simple to make
harsh garden
A simple user_name & user_hookpath should be enough
sick cave
just make sure you're not executing user-writable scripts as root 
harsh garden
then, execute as the user everything in the ${user_hookpath} that is +x'd
