QStorageInfo.mountedVolumes() gives incomplete list on macOS

QStorageInfo.mountedVolumes() does not detect volumes mounted via /etc/fstab or /etc/auto_master. As far as I can it only detects network mounts created via Finder.

Here is a link to the relative section of code.

The problem is in the option kCFURLEnumeratorSkipInvisibles. Using virtually any other option in the CFURLEnumeratorOptions results in a complete listing of mounts.

I was able to recreate the Qt behavior in a Swift playground file with the following contents

import Cocoa

let options = CFURLEnumeratorOptions.skipInvisibles
let volumes = CFURLEnumeratorCreateForMountedVolumes(nil, options, nil)!

var paths = [CFString]()
var result = CFURLEnumeratorResult.success
var urlProperty : Unmanaged<CFURL>?
var errorProperty : Unmanaged<CFError>?

repeat {
    result = CFURLEnumeratorGetNextURL(volumes, &urlProperty, &errorProperty)
    if result == CFURLEnumeratorResult.success {
        if urlProperty != nil {
            let unpackagedUrl = urlProperty!.takeRetainedValue() as CFURL
            let urlString = CFURLCopyFileSystemPath(unpackagedUrl, CFURLPathStyle.cfurlposixPathStyle)
            paths.append(urlString!)
        }
    }
} while result != CFURLEnumeratorResult.end
print(paths)

Here is a link to all the possible options that CFUrlEnumeratorCreateForMountedVolumes can be called with: https://developer.apple.com/documentation/corefoundation/cfurlenumeratoroptions

I suggest a different option is considered such as skipPackageContents.

Another quick sanity check is to mount a network share via /etc/fstab or /etc/auto_master and then run mount from the terminal, and compare that to the output of QStorageInfo.mountedVolumes().
