fuse-t is quite interesting! I have added a few comment on the code.

However, to get this merged, you will have to send the changes via gerrithub ( see
https://github.com/hanwen/go-fuse/blob/master/CONTRIBUTING )

[rfjakob]

BTW, this could be tested on Github Actions, right?

I don't have experience with Github Actions, but testing should be easy. fuse-t can be installed with homebrew before running tests and that's the only requirement

[macos-fuse-t]

Most of the comments are addressed. Please take a look at the new commits

[hanwen]

thanks for your contribution!

As discussed above, it would be swell to get a gerrithub review for this.

As an aside, I've been mulling implementing NFS natively directly in go-fuse, but I haven't found a good description of the NFS protocol yet. I guess you'd rather see people pay you for fuse-t, but maybe you can comment on how much complexity the NFS <-> FUSE bridge involves?

When do you plan add this changes to master branch ?

[hanwen]

I do not have concrete plans; my comments in the code review have gone unanswered.

[macos-fuse-t]

I don't have time for this. But @libor13 can use the forked repo

[libor13]

Please add support for -o location option added in fuse-t 1.0.22
Option should be added in ./fuse/mount_darwin.go in function mount_fuset()

That's really a pity! :-(

Just FYI: I tried to sign up on Gerrit (I had already signed the Google's CLA, which is also trivial to do), and, after five minutes, I had everything set up for my own repositories. That's all it takes, it won't eat much from your precious time...

[libor13]

@macos-fuse-t do you have plan to merge current changes from hanwen:master to your branch ?
@hanwen is there something new about using fuse-t in hanwen/go-fuse project ?

When I try to mount virtual drive from gocryptfs using last source from macos-fuse-t/go-fuse I got this error:

Any update @macos-fuse-t @hanwen? That would definitely be a good addition to integrate fuse-t since the opening of this PR a year ago.
