I noticed Debian does this by default and Arch wiki recommends is citing improved security and upstream.
I don’t get why that’s more secure. Is this assuming torrents might be infected and aims to limit what a virus may access to the dedicated user’s home directory (/var/lib/transmission-daemon
on Debian)?
Not yet, but if every system was only protected against what already happened instead of also what could happen, we’d get hacked a lot more often!
