Why doesn't KDE's device auto mount just edit the /etc/fstab file?
Every time I tried to enable the device auto mount on my second hard drive, it never worked. I always had to manually mount it through KDE's GUI whenever I wanted to access it's content.
I later researched and found out that I could edit the /etc/fstab file with my second hard drive's UUID, which caused it to always mount on startup as I wanted.
So my question is, why doesn't KDE auto mount also replicate this process of editing the /etc/fstab?
The KDE auto mount never worked on plasma 6, I believe it's something related to wayland (even though I don't understand how they could be related).
The "modern" way would use systemd to implement the mounting, either on a system or a user level.
Using fstab can be problematic when the drive is missing or otherwise not available during boot.
What's used under the hood for this is udisks, the same thing used by other file managers to achieve mounting capabilities. It allows you to mount devices without needing to mess with something cryptic and archaic like fstab and doesn't require root.
You can always keep using fstab of course since it works, but in that case you probably also want to use fstab systemd integration.
