It means the ACPI firmware gets to see 'Linux' as the string identifying
your OS.  What that means depends entirely upon the writers of the
firmware, which usually only test Windows.

IMHO the better choice would be the default, i.e. not setting acpi_osi
explicitly and letting the kernel determine what is best.

It might be useful as a workaround for specific pieces of hardware, but
other than that, no.

must be true).
