Bug#449220: mdadm: checkarray from cron runs twice when daylight saving time changes

[Ariel]

Package: mdadm
Version: 2.5.6-9
Severity: normal

Checkarray from cron runs at 1:06AM, this means it runs twice when daylight
saving time changes in the winter, and worse it doesn't run at all in the
summer when the clock jumps from 1 to 2.

I suggest moving to 2:06 (unless there are some locals where that also
wouldn't work).
