Are Steam games kind of sandboxed?
by Markus Schaaf 10 Jul '25

10 Jul '25

Hi all, I am trying to access a folder directly beneath the root folder of my computer from inside a game (Symphony), using Steam Linux Runtime (no Windows emulation like Proton). Strangely that particular folder is missing (some others like /boot and /opt too). Then there is a folder /overrides that does not exist in /. So this is some kind of sandbox, but I have no idea where to look, if I want to whitelist or link other folders there. Can anybody help? BR Markus

Updated on 25th to 6.15.3 + firmware (fine), update tonight to 6.15.4 + firmware, network not up, dhcpd4 fails?

All, I have my Arch server that has been running for a decade, updates weekly, never misses a beat. It has been so long since I've had an issue with it, I thought Arch had finally reached Linux rolling release nirvana. Then, for reasons I can't explain, the update tonight (an hour ago), failed to start dhcpd4. I can't ping the box, I have to log in locally and I find the network interface enp5s0 'down' - that's not happened since Arch was installed. So I bring the interface up: # ip link set enp5s0 up Presto, network is up, and well. So I try starting dhcpd4 and it fails "cannot create /run/dhcpd4/dhcpd.pid". There is no /run/dhcpd4 directory. So I created it and manually started dhcpd4 without -q and all starts fine and it is now happily handing out addresses and updating the bind DNS zone for about 60 clients. What happened? I did not install or uninstall anything new. I simply did a "pacman -Syu" to update the system.

Most of the time I admin this box remotely. Having it reboot and not reliably come back up isn't an option. Is there some issue with the new firmware and network devices? The network device uses the r8169 driver is that is an issue, it used the r1868 driver in the past.
