The lucreate -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. 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. To create the same number of files systems that is on your current system, you must specify one -m option for each file system to be created.
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 that is specified by the -m option. If you specify the -m option twice, you create two file systems. 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.
