root_device Profile Keyword

root_device slice

root_device can be used with both the initial installation and upgrade options.

root_device designates the system's root disk. See "How the System's Root Disk Is Determined" for more information.

For Upgrade:

root_device designates the root file system (and the file systems mounted by its /etc/vfstab file) to be upgraded. You must specify root_device if more than one root file system can be upgraded on a system. slice must be specified in the form cwtxdysz or cxdysz.

Example:

root_device c0t0d0s2

If you specify root_device on a system with only one disk (not required), the root_device and the disk must match. Also, any filesys keywords that specify the root file system must match root_device.
