root_device Profile Keyword

root_device slice

You can use root_device with both the initial installation and upgrade options.

root_device designates the system's root disk. "How the System's Root Disk Is Determined" contains additional information.

For an 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. You must specify slice in the form cwtxdysz or cxdysz.

Example:

root_device c0t0d0s2

If you specify root_device on a system with only one disk, the root_device and the disk must match. Also, any filesys keywords that specify the root (/) file system must match root_device.
