To add to this: The help text should IMO contain
- that a test for faulty RAM is being added if Y,
- that this feature can be controlled by the boot parameter
(and, per the parameter's default, is normally off),
- how many loops with which data patterns are performed depending
on the boot parameter value,
- how long this might take (so that nobody who hears of this for
the first time enables it e.g. on a server which is supposed to
not take too long to reboot),
- how reliable the results of this test are (I presume that some
faults can only be found by many repeated re-runs of the memory
tester),
- that saying Y slightly (?) increases the size of the kernel image
but does not influence the kernel size after boot-up is completed.
