Mount Options – How to Set Default Auto Mount Options for Removable Media

I think you're looking for pmount.

If you want automatic mounting upon insertion, see Automounting USB sticks on Debian.

If your system uses udisks2, that's the preferred way of reacting to the insertion of a removable storage device. See the Arch Wiki for configuration tips for Udisks.

Otherwise, the program that reacts when a new device appears is udev, so automatic mounting is triggered by a udev rule. The usbmount package provides udev rules to automatically mount USB storage devices and a few others. Calling mount from udev rules doesn't work for FUSE filesystems (such as ntfs-3g), so use udisks if you need that.

You cannot automatically unmount media when they are removed because causality doesn't work that way. The media must be unmounted before it is removed. For read-only media, you can get away with unmounting after removal, although this might confuse some applications if they have files open on the suddenly-vanished filesystem. For writable media, if you unplug a mounted filesystem, data corruption is likely.

Take a look at the AutoFS service which can facilitate more elaborate automounting scenarios than can be accomplished via the /etc/fstab file.

• AutoFS - ArchLinux wiki

You can do a variety of things such as automounting devices via a script, when a directory path is accessed.

/media/ssh      /etc/autofs/auto.ssh    --timeout=60

In this scenario if someone were to access /media/ssh the script /etc/autofs/auto.ssh would execute and "mount" whatever directory they attempted to access under /media/ssh.

# /etc/autofs/auto.ssh
servername     -fstype=fuse,rw,allow_other,IdentityFile=/home/username/.ssh/id_dsa :sshfs\#username@host\:/

After 60 secs. of inactivity autofs will unmount the directory.
