Nope it doesn’t add anything for me. The _netdev option tells mount to wait until the network is connected before attempting to mount. And the nofail option tells it not to error or block the process that called it if the mount doesn’t work or is delayed.
Now if the mount contains your etc or other critical config files, it could cause problems and maybe you want to wait, so don’t want the nofail. And of course this kind of thing is somewhat OS specific depending on what boot system and service manager, etc., is used, so YMMV, but on Fedora, Rocky, and Ubuntu, it has worked for me for many years.
Most could, but most are also designed not to because adding a virtualization type of layer allows for ways to circumvent it. Anticheat needs to trust the environment it is running in so it can rely on the information. Wine is designed to replicate things it trusts in Windows, but not actually necessarily replicate the way the kernel actually does those things, so the things they are relying on might not mean the same thing as the do in Windows. So they’d need to analyze and possibly implement things a bit differently. This takes time and money and for companies like this, the customer isn’t the user, so they have little reason to cater to users needs. Pro gaming and a few online game companies are their primary customers and they generally don’t want to support Linux anyway.
