From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Ah ok i think i get why it doesn't work through the auto mount, but i still don't understand why it works completely fine if i mount it through steam? What is different when steam mounts it?
I don't know for sure, but I have an idea.
By default, Steam creates wineprefixes in
~/.steam/steam/steamapps/compatdata/GAME_ID
. This is located in the user home, which should be a Linux filesystem (ext4, btrfs, and similar). If the drive is mounted statically through fstab, the prefixes are created on the mounted drive. If the drive is mounted dynamically, Steam might think it's a USB stick, likely with a FAT32 filesystem, and preemptively create the prefixes inside the user home to ensure compatibility.I'll have to do some testing once I get home.
This could very well be the anwser. there are in fact c: and z: in
~/.steam/steam/steamapps/compatdata/0/pfx/dosdevices
although i couldn't find an indicator that those are actually in use when launching a game through steam
They're definitely both used. When a program is started in a Wine environment, those symlinks are the only way it can access the filesystem: game files in
.../steamapps/common
throughz:
; settings and saved games (normally in the Windows user's home directory) throughc:
.You can run
wine explorer.exe
to open a Windows Explorer implementation and check out what the Linux filesystem looks like in Windows. You can even add new lettered drives usingwinecfg
, although I wouldn't try it with Steam's prefixes.
