Use the ^ and v keys to select which entry is highlighted.
Press enter to boot the selected OS, 'e' to edit the
commands before booting, or 'c' for a command-line.
After the rollback boot menu entry is selected, the system boots the old kernel software, but the rollback must be manually confirmed on the console to commit the rollback, which effectively removes all changes to the system that have happened since, as described earlier. The confirmation step is similar to the following example:
SunOS Release 5.11 Version ak/generic@2011.04.24.4.2,1-1.28 64-bit
Copyright (c) 1983, 2010, Oracle and/or its affiliates. All rights reserved.
System rollback in progress.
Rollback to: ak/nas@2011.04.24.4.2,1-1.28
Proceed with system rollback [y,n,?]
