> It seems in Force10 FTOS9 the mod time on  ".." on the flash changes every
> time a login happens.  So everytime RANCID logs in, it triggers an alert.
>  Has anyone else seen this and stopped it from triggering? Just to note, I
> am not seeing this on the FTOS 8 switches (S55) only the FTOS 9 right after
> upgrade (S4810P stacked). Below is a few examples.
