I am not familiar with the inner workings of this mechanism. Please let me know if I need to test anything.

Output of your mount command and udisks2 automatic mount are equal, but results are not.

That seems to have been the case on Leap 42.3 but as mentioned on 15.0 permissions are 777 when mounting as user.

Background for these permission can be found in Documentation/filesystems/vfat.txt in the kernel sources: --> umask=### -- The permission mask (for files and directories, see umask(1)). The default is the umask of current process. dmask=### -- The permission mask for the directory. The default is the umask of current process. fmask=### -- The permission mask for files. The default is the umask of current process. --< Since the windows fat filesystems doesn't support file permissions, the above default from the umask are used. It seems that the mount process doesn't have an umask, so the permissions get set to 777. Reason for the difference between 42.3 and 15 is a version update from the (very outdated) udisks version 2.1.6 to version 2.6.5. Version 2.6.5 ships the following upstream changes: --> commit d15f4391042ccc09c848f9eb93a6dd75dd1c514b Author: Martin Pitt Date: Fri Nov 25 10:04:42 2016 +0100 exfat: Drop umask=0077 default The parent mount point dir (/run/media/user) already controls access permissions, so there is no need to set umask to 077 for exfat either. This makes UDISKS_FILESYSTEM_SHARED="1" actually work for exfat.

This makes UDISKS_FILESYSTEM_SHARED="1" actually work for these file systems. https://launchpad.net/bugs/453605 --< This drop results in getting the same permissions like with manual mounts. You can find more background about the reasoning in the debian bug report at: https://bugs.launchpad.net/gvfs/+bug/453605 What is the actual problem you are seeing with this? As outlined in the patch, the mount below a dedicated user directory already controls access to the files on the removable medium. There should be no need to set the permission for each particular file/directory on the medium. -- You are receiving this mail because: You are on the CC list for the bug.
