for evaluation of zIPL environment variables in the kernel command line.
This option requires an argument, which has to be a string of the form
"nSX", where optional number 'n' indicates the boot menu entry, and optional
token 'SX' specifies the active namespace. This token consists of a mandatory
leading capital 'S' and of an optional trailing character 'X', which is
either any decimal digit, indicating ID of the active site, or a capital 'S'.
In the last case, ID of the active namespace is determined as the SSID
(Subchannel Set ID).
If the menu entry is omitted in the argument, then the default menu entry
is used. If the 'X' is omitted, or the whole token 'SX' is omitted, then the
common namespace of the installed zIPL environment block will be activated.
