Become superuser or assume an equivalent role.
Create the directory you want to mount as an LOFS file system, if necessary.
# mkdir loopback-directory |
Grant the appropriate permissions and ownership on the newly created directory.
Create the mount point where you want to mount the LOFS file system, if necessary.
# mkdir /mount-point |
Mount the LOFS file system.
# mount -F lofs loopback-directory /mount-point |
loopback-directory |
Specifies the file system to be mounted on the loopback mount point. |
/mount-point |
Specifies the directory on which to mount the LOFS file system. |
Verify that the LOFS file system has been mounted.
# mount -v |
The following example illustrates how to create, mount, and test new software in the /new/dist directory as a loopback file system without actually having to install it.
# mkdir /tmp/newroot # mount -F lofs /new/dist /tmp/newroot # chroot /tmp/newroot newcommand |
You can set up the system to automatically mount an LOFS file system when it boots by adding an entry to the end of the /etc/vfstab file. The following example shows an entry in the /etc/vfstab file that mounts an LOFS file system for the root (/) file system on /tmp/newroot.
/ - /tmp/newroot lofs - yes - |
Make sure the loopback entries are the last entries in the /etc/vfstab file. Otherwise, if the /etc/vfstab entry for a loopback file system precedes the file systems to be included in it, the loopback file system cannot be mounted.
For more information on the /etc/vfstab file, see Field Descriptions for the /etc/vfstab File.
