Enabling users to mount filesystems

Enabling users to mount filesystems

In the Filesystem Manager, select Add Mount Configuration or Modify Mount Configuration from the Mount menu, then select Yes for ``Can Users Mount''. 


NOTE: You can also enable user mounting transparently using automount(NADM). If you create an automount map for a filesystem exported from a remote machine, the filesystem is mounted automatically whenever the filesystem or one of its files is accessed. Such a mount is transparent to the user, and the filesystem unmounts automatically after a certain period of inactivity. See Chapter 15, ``Configuring the NFS automounter'' in the Networking Guide for details.

Under normal circumstances, only root, programs run as root, and users with the sysadmin and backup (or queryspace) authorizations can mount and unmount filesystems with the Filesystem Manager or the mount(ADM) and umount(ADM) commands. However, when you select this mount option for a filesystem, you can enable users to mount and unmount the filesystem using the mnt(C) and umnt(C) commands. The mnt command allows users other than root to access the functionality of mount for that particular filesystem.

For example, if you enable users, they can mount the /usr filesystem by entering:

mnt /usr

To unmount the filesystem, users enter:

umnt /usr


NOTE: For reasons of security, it is not a good idea to allow users to mount floppy filesystems.

Instruct your users in these proper mounting procedures:
