KDE Neon using tmpfs for /tmp seems like an horrible idea? (lemmy.kde.social)

I get the idea behind it for sure but why use our available ram for this? I thought whatever init functionality would just wipe clean /tmp at boot.

Right now what I'm looking at is that if a system has 16gbram KDE Neon uses half of it for /tmp.

The thing is applications could output to /tmp for a plethora of reasons that could maximize that. Whether you are a content creator or processing data of some sort leaving trails in /tmp the least I want is my ram being used for this thing regardless.

Basically if you drop-in a 10GB file in /tmp right now (if your setup has tmpfs active) you will see a 10GB usage in your htop. Example in https://imgur.com/a/S9JIz9p

I'm not here to pick a fight but as a new KDE Neon user I'm scratching my head on the why after years in Arch Linux.

It's default since systemd afaik. I think systemd-tmpfiles manages this. It's never been a problem for me, it pretty much remains fairly empty most of the time. Most things like sockets are in /run which is also tmpfs.
