The lucreate command that is used with the -m option specifies which file systems and the number of file systems to be created in the new boot environment. You must specify the exact number of file systems you want to create by repeating this option. For example, a single use of the -m option specifies where to put all the file systems. You merge all the file systems from the original boot environment into the one file system specified by the -m option. If you specify the -m option twice, you create two file systems. When using the -m option to create file systems, follow these guidelines:
You must specify one -m option for the root (/) file system for the new boot environment. If you run lucreate without the -m option, the Configuration menu is displayed. The Configuration menu enables you to customize the new boot environment by redirecting files onto new mount points.
Any critical file systems that exist in the current boot environment and that are not specified in a -m option are merged into the next highest-level file system created.
Only the file systems that are specified by the -m option are created on the new boot environment. If your current boot environment contains multiple file systems, and you want to have the same number of file systems in the new boot environment created, you must specify one -m option for each file system to be created. For example, if you have file systems for root (/), /opt, and /var, you would use one -m option for each file system on the new boot environment.
Do not duplicate a mount point. For example, you cannot have two root (/) file systems.
