boot_osflags
The boot_osflags environment variable sets the default boot flags and, for
OpenVMS, a root number.
Boot flags contain information used by the operating system to determine
some aspects of a system bootstrap. Under normal circumstances, you can use
the default boot flag settings.
To change the boot flags for the current boot only, use the flags_value
argument with the boot command.
The syntax is:
set boot_osflags flags_value
The flags_value argument is specific to the operating system.
Tru64 UNIX Systems
UNIX systems take a single ASCII character as the flags_value argument.
Load operating system software from the specified boot device (autoboot). Boot to
a
multiuser mode.
Prompt for the name of a file to load and other options (boot interactively). Boot to
i
single-user mode.
Stop in single-user mode. Boots /vmunix to single-user mode and stops at the # (root)
s
prompt.
Full dump; implies "s" as well. By default, if UNIX crashes, it completes a partial
D
memory dump. Specifying "D" forces a full dump at system crash.
