Category "Beta"

With NoMAD version 1.1 just a short ways around the corner, we wanted to start sharing the Shares preference file… see what we did there!?!

Note: As a beta this file format is still subject to change… but we wanted to give you an idea of what was coming.

What is this?

With 1.1 NoMAD will be able to arbitrarily mount shares specified in a preference file. Since the shares are rather different than the rest of the NoMAD preferences, we’ve put them into a new plist to make things easier.

Where does it go?

Currently this preference is at menu.nomad.shares, but as with all things beta, this may change.

How do you make it?

There are 3 top-level objects in the file.

1. Version – this is the version number of the file format. Currently the only version is 1

2. HomeMount – This is a Dictionary of attributes for if the user’s home profile should be mounted.

Groups – [String] – Only mount the home for members of these AD groups
Mount – Bool – Mount automatically or not
Options – [String] – Array of mount options defined below

3. Shares – [Dictionary] – An array of dictionaries with each dictionary defining a mount point and associated attributes. Below is what goes into each Dictionary
AutoMount – Bool – Is the share automatically mounted
ConnectedOnly – Bool – Is the share only mounted when on the AD domain
Groups – [String] – An array of AD group names. This share will only automount for members of that group
LocalMount – String – A local mount point
Name – String – The name of the share as it will appear in the NoMAD menu item
Option – [String] – Array of mount options defined below
URL – String – The actual URL of the mount point in the form of “smb://dc1.nomad.test/Homes”

Options

First off huge thanks to @frogor for having figured these out. Note that most of these are probably not very useful or safe. Please use at your own risk. The primary ones that most admins will care about are MNT_RDONLY, MNT_DONTBROWSE and MNT_NOEXEC.

"MNT_RDONLY" - Mounts the share read only
"MNT_SYNCHRONOUS" - All I/O to the file system should be done synchronously.
"MNT_NOEXEC" - Prohibts execution of code from the share
"MNT_NOSUID" - Do not allow set-user-identifier or set-group-identifier bits to take effect.
"MNT_NODEV" - Do not interpret character or block special devices on the file system.
"MNT_UNION" - Causes the namespace to appear as the union of directories of the mounted filesystem with corre-
sponding directories in the underlying filesystem.
"MNT_ASYNC" - All I/O to the file system should be done asynchronously.
"MNT_CPROTECT" -
"MNT_EXPORTED" - Filesystem is exported
"MNT_QUARANTINE" - File system is quarantined
"MNT_LOCAL" - File system is stored locally
"MNT_QUOTA" - Quotas are enabled
"MNT_ROOTFS" - Identifies the root filesystem
"MNT_DOVOLFS" - Filesystem supports volfs (deprecated flag in Mac OS X 10.5)
"MNT_DONTBROWSE" - Does not display the share in the Finder
"MNT_IGNORE_OWNERSHIP" - Ignore ownership information on file system objects
"MNT_AUTOMOUNTED" - Set flags on the mountpoint to indicate that the volume has been mounted by the automounter.
"MNT_JOURNALED" - Mount filesystem journaled
"MNT_NOUSERXATTR" - User extended attributes not allowed
"MNT_DEFWRITE" - Filesystem should defer writes
"MNT_MULTILABEL" - Support for individual labels
"MNT_NOATIME" - Do not update the file access time when reading from a file.
