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.
