Hmm, after some more research, I found that drvfs support for various filesystems / filsystem drivers seems to be rather incomplete. There are multiple issues on Microsoft’s WSL Github repo about such limitations. (I’m just puzzled by the fact that, AFAIR, it worked just fine the last time I had a need for it.)
So for now the easiest workaround is to actually synchronize the library and access those files from within WSL.
Good to know, thanks for the tips.
As for the “Windows users”, that I’ll have to reject emphatically
I’m somewhat forced to use it, since my current Thinkpad is having some annoying suspend/resume reliabilty issues with Linux. (Maybe even dangerous: it seems suspended but is heating up…) But that’s my first real exposure to Windows in decades. WSL makes it bearable.
Anyway, did you actually try what you’re proposing? I’d really be interested to hear, since my understanding was that missing FUSE support was one of the many, many limitations of WSL when compared to native Linux. I’ve given up on trying more advanced things with WSL. On the one hand it’s truly marvelous, on the other hand it’s frustrating as hell if you’re coming from a native system.
