ADMIN_MOUNT feature provides support for the built-in mount and umount commands of C_INIT(1M). If the feature is not configured, the built-in C_INIT command will display an error message. This feature affects the content of the
ADMIN system actor. For more information on the
mount service, refer to mount(1M). This feature provides support
to mount and unmount UFS, MS-DOS and NFS file systems. If this feature is not set, there will be no way to run a command to mount a file system within the target system. In this type of configuration, file systems will have to be mounted by user provided applications embedded within the boot image using the mount(2POSIX) system call.
For more details, see ADMIN_MOUNT(5FEA).
