OpenVMS Systems
OpenVMS systems require an ordered pair, separated by a comma, as the flags_value
argument: root_number, boot_flags.
root_number Directory number of the system disk on which OpenVMS files are located.
For example:
root_number

multiple boot flags, add the flag values (logical OR). For example, the flag
value 10080 executes both the 80 and 10000 flag settings. See Table 3–1.
