If I remove nomixupload, the error changes to:

fuse: Unknown parameter 'url'

Does this only happen via fstab or can you reproduce the symptoms when directly invoking s3fs?

I have the same issue using alpine 3.23 (with use_path_request_style), the problem appears only when using fstab.
Mounting with s3fs works well.

Only happen via fstab, and it appears that fuse refuses to resolve these s3fs parameters.

For reference only, modifying the fstab entry to the following format can resolve the issue:

s3fs#bucket-name /mount-path fuse3 _netdev,allow_other,url=https://s3.xxx.xxx,passwd_file=/etc/passwd-s3fs 0 0

Are you sure? The error I'm seeing is: "unknown filesystem type 'fuse3'."
Got it — I need to install the fuse3 package.
