Hello Nick, Eitan,


@Nick
WRT security, I have to agree with borjam's comment [1] about making this a
loader-time tunable.
WRT different values, I would think it a shore to implement "warn again
after X minutes".
Certainly for the needs referenced by PR 166255, this would be overkill.


@Eitan
The problem with adjusting this at syslog (or rsyslog)'s level is that you
effectively generate the message, then have to expand even more work to
actually suppress it, making your machine work twice for no reason.
