Can't remount after unmount in the same process about cgofuse HOT 3 CLOSED

BTW, the latest version of WinFsp should now support multiple FUSE file systems in the same process.

WinFsp 2018.2 B2

I believe you have hit an inherent limitation of the WinFsp-FUSE layer: you can only have one file system per process. The reason is explained below.

There is no such limitation in the core WinFsp layer. You can have as many file systems as you want in a process either simultaneously or one after another. However file systems in Windows need to often be run as services and for this reason the core WinFsp layer also provides an API to facilitate this.

The WinFsp-FUSE layer uses both the file system and service API's. This way a WinFsp-FUSE file system can easily become a Windows service. There is a problem: once a Windows process starts acting as a service and then stops being a service, it cannot become a service again (this is true of the WinFsp Service API, although I do not remember if this is an inherent limitation of the Windows Service API).

You see where I am going with this. Having FUSE file systems being able to act as Windows services is valuable. The downside is that you can only have one FUSE file system per process.

So this is not a limitation of cgofuse, but rather a limitation of the WinFsp-FUSE layer. However it is not a limitation that I can fix as FUSE file systems would lose the "free" ability to act as Windows services.

I see, thanks for explaining that.

I'll stop beating my head against that particular wall then and think of a work-around ;-)

It is just for the test suite in rclone - it isn't something that regular users will do so a work-around is fine!
