lutab

lutab(4)																  lutab(4)

NAME

       lutab - list of boot environments

SYNOPSIS

       /etc/lutab

DESCRIPTION

       The  file /etc/lutab is a list of the boot environments (BEs) configured on a system. There are two entries for each BE. These entries have
       the following form:

       BE_id:BE_name:completion_flag:0
       BE_id:root_slice:root_device:1

       The fields in the lutab entries are described as follows:

       BE_id	       A unique, internally generated id for a BE.

       BE_name	       The user-assigned name of a BE.

       completion_flag Indicates whether the BE is complete (C) or incomplete (NC). A complete BE is one that is  not  involved  in  any  copy	or
		       upgrade operation. A BE can be activated or compared only when it is complete.

       0	       Indicates first of two lines.

       BE_id	       As described above.

       root_slice      Designation of the root slice.

       root_device     Device on which the root slice is mounted.

       1	       Indicates second of two lines.

       The lutab file must not be edited by hand. Any user modification to this file will result in the incorrect operation of live upgrade.

SEE ALSO

       lu(1M), luactivate(1M), lucreate(1M), lucurr(1M), lufslist(1M), lustatus(1M), luupgrade(1M), attributes(5), live_upgrade(5)

WARNINGS

       The  lutab  file  is  not  a public interface. The format and contents of lutab are subject to change. Use lufslist(1M) and lustatus(1M) to
       obtain information about BEs.
